A solid circular cylinder has a base radius 5 cm and a height 12.5 cm. Find the approximate increase in the surface area of the cylinder when the radius of the base increases to 5.05
Answers
Answer:
19.72 cm²
Step-by-step explanation:
A solid circular cylinder has a base radius 5 cm and a height 12.5 cm.
The volume of cylinder is given by :
[tex]V=\pi r^2 h\\\\=3.14\times (5)^2\times 12.5\\\\=981.25\ cm^2[/tex]
When r = 5.05, new volum becomes,
[tex]V=\pi r^2 h\\\\=3.14\times (5.05)^2\times 12.5\\\\=1000.97\ cm^2[/tex]
Increase in area = 1000.97 - 981.25 = 19.72 cm²
So, the increase in surface area of the cylinder is equal to 19.72 cm².

This is solving quadratic functions by square roots btw
Answers
Multiply both sides by 4 to get rid of the four on the left.
3x^2 = 192
Divide both sides by 3
x^2 = 64
The square root 64 to get x
Remember there are two answers
x = 8 and x = -8
Answer:
x = 8
Explanation:
[tex]\frac{3x^2}{4} =48[/tex]
multiply both sides by 4: [tex]3x^2=192[/tex]
divide both sides by 3: [tex]x^2=64[/tex]
take the square root:
[tex]\sqrt{x^2} = \sqrt{64} \\x=8[/tex]

How much time is between 2:30 pm and 4:15pm?? I need an answer quick!!
Answers
Answer:
Step-by-step explanation:
First do 4 -2 to get 2. Then do 30-15 to get 15. It’s 2:15.
You can also do this on a calculator by doing 4.15-2.30. You get 1.85
Remember that time is only up to 60 So you have to subtract 15 from 85 to get 60. So it’s 2 hours and 15 minutes. Hope this helps!
Find the coordinates of point M, that partitions the directed line segment SY from S(4,2) to Y(-4,-6) in a ratio of 1/3.
Answers
Answer:
the coordinates of point M = (2,0)
Step-by-step explanation:
Given;
point S along the segment, = S(4,2)
point Y along the segment, = Y(-4, -6)
ratio of the partition = ¹/₃
total ratio = 1 + 3 = 4
The midpoint of segment SY is calculated as follows;
[tex]mid-point (o) = \frac{x_1 + x_2}{2} ,\ \frac{y_1 + y_2}{2}\\\\ mid-point (o) = \frac{4 + (-4)}{2} , \ \frac{2+ (-6)}{y} \\\\mid-point (o) = \frac{0}{2} , \ \frac{-4}{2} \\\\mid-point (o) = (0, \ -2)[/tex]
The coordinates of point M is calculated as follows;
point M divides the segment into 4 equal parts with point O as the mid-point.
M
S--------------|-------------------O-------------------|-------------------Y
|SO| = |OY|
[tex]The \ mid-point \ of \ SO = M\\\\Point \ S = (4,2) \\\\Point \ O = (0,-2) \\\\Point \ M = \frac{4 + 0}{2}, \frac{2 - 2}{2} \\\\ Point \ M = 2, 0 \\\\M = (2,0)[/tex]
Therefore, the coordinates of point M = (2,0)

At the city triathlon, athletes bike 110 miles, run a 23.5 miles marathon, and swim. If the total distance of this triathlon is 135.7 miles, how far de the athletes swim?
Answers
Answer: 2.20 miles
Step-by-step explanation:
The triathlon involves the bike race, swimming and the marathon.
You are given the distance for the marathon, the biking and the total distance.
Total distance = Swimming + Marathon + Biking
135.7 = Swimming + 23.5 + 110
Swimming = 135.7 - 23.5 - 110
Swimming = 2.20 miles

How was ice able to fall even though the temperature was much warmer than freezing?

Caterers made 272 cups of punch for a party. They will distribute the punch equally into 6 bowls. How many cups of punch will each bowl have? A. B. C. D.
Answers
Answer:
45.33 cups.
Step-by-step explanation:
272 divided by 6 gives this answer
The number of cups of punch each bowl will have is given by the equation A = 45.3 cups
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of cups of punch in each bowl be represented as A
Now , the equation will be
The total number of cups of punch = 272 cups
The number of bowls = 6 bowls
So , the number of cups of punch in each bowl A = total number of cups of punch / number of bowls
Substituting the values in the equation , we get
The number of cups of punch in each bowl A = 272/6
The number of cups of punch in each bowl A = 45.3 cups
Therefore , the value of A is 45.3 cups
Hence , the number of cups in each bowl is 45.3 cups

State the slope and y-intercept for the graph of the equation -8x + y = -12.
Show your work!!
Answers
Answer:
Slope is 8 and Y-Intercept is -12
Step-by-step explanation:
Move the -8x over to the right side by adding it, You are now at
y=-12+8x
Move these around and you are now at
Y=8x-12
Answer:
Step-by-step explanation:
Remark
y must have a numerical coefficient of 1. This equation does. If it does not, then you must divide through by whatever is in front of the y.To read the slope, you must have x and its coefficient on opposite sides of the equal sign. So you get y = 8x - 12 when you add 8x to both sidesNext, the y intercept is found when x = 0y = 8x - 12y = 8(0) - 12y = - 12The y intercept is -12 or in point form (0, - 12)Answer
slope = 8
y intercept = - 12
