A cylinder has a volume of 198 cm3, and its base has an area of 22 cm2. What is the height of the cylinder? V= πr²h
Answer:
The height of cylinder is 9 cm
Step-by-step explanation:
Volume of cylinder = 198 cm³
Base Area = 22 cm²
We need to find height of the cylinder
The formula used is: [tex]Volume\:of\:cylinder=\pi r^2h[/tex]
Where [tex]Base\: Area = \pi r^2[/tex]
First we need to find radius r
[tex]Base\: Area = \pi r^2\\22=3.14\: r^2\\r^2=\frac{22}{3.14}\\r^2=7\\Taking\: square\: root\: on\: both\: sides\\\sqrt{r^2}=\sqrt{7}\\r=2.656[/tex]
So, we get radius r = 2.656
Putting values of volume and radius are to find height
[tex]Volume\:of\:cylinder=\pi r^2h\\198=3.14(2.656)^2h\\h=\frac{198}{22}\\h=9[/tex]
So, the height of cylinder is 9 cm

39,000 over 12 = ?? Also, show your work so I can do the rest of these myself
Answer:
3,250
Step-by-step explanation:
Let's go from left to right, using multiple of 12 times a power of 10 in the process.
What is the closest multiple of 12,000 (12 * 10^3) to 39,000 without going over? That's 3 (36,000). That's the thousands digit in this answer.
12,000 * 3 = 36000
39000 - 36000 = 3000
What's the closest multiple of 1,200 (12 * 10^2) to 3,000 without going over? That's 2 (2,400). That's the hundreds digit.
1,200 * 2 = 2,400
3,000 - 2,400 = 600
What is the multiple of 120 (12 * 10) closest to 600 without going over? That's 5 (600, it's even!). That's the tens digit. Since it goes evenly, 0 is the ones digit.
120 * 5 = 600
600 - 600 = 0.
The answer to 39,000 over 12 is 3,250.

19. Mel cleans houses.
She earns $7.50 every hour that she dusts.
She earns $10.00 every hour that she scrubs floors.
She scrubbed floors for 1 1/2 hours and dusted for hours.
How much money did Mel earn?
Answer: $45
Step-by-step explanation: 10 for the hour she scrubbed the floor half of that which is 5 for the half hour she scrubbed so that would be $15, then 7.50 times 4 for the hours she dusted which would be 30, and 30 plus 15 is 45
The shed in Stephanie’s back yard has a door that measures 6 feet high and 3 feet wide. Stephanie would like to buy and store a ladder in the shed diagonally. What is the maximum height, in feet, of a ladder she can buy to fit through the door?
Answer:
the answer is 6 ft hope it helps
The maximum height, in feet, of a ladder she can buy to fit through the door is, 6.7 feet
What is Pythagoras theorem?
The Pythagoras theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the square of the other two sides.
We have to given that;
The shed in Stephanie’s back yard has a door that measures 6 feet high and 3 feet wide.
Now, By using Pythagoras theorem;
The length of a ladder she can buy to fit through the door is, x
⇒ x² = 6² + 3²
⇒ x² = 36 + 9
⇒ x² = 45
⇒ x = √ 45
⇒ x = 6.7 feet
Thus, The maximum height, in feet, of a ladder she can buy to fit through the door is, 6.7 feet
