the radius of a circle is 8 what is the area of the circle? pls show work

Answers

Answer 1

Answer:

201.06

Step-by-step explanation:

A=πr2=π·82≈201.06193

Answer 2

Answer:

201.14 ≈ 201 unit²

Step-by-step explanation:

Area of circle = πr², where π is either 3.14 or 22/7 or 355/113. Mostly it is 22/7.

=> area of circle = (22/7) (8)² unit²

=> area of circle = (22 x 64)/7 unit²

=> area of circle = 201.14 unit²

If we take π = 3.14

=> area of circle = (3.14)(8)² = 200.96 unit²

point(3,2) lies on the line given by the equation 5x-y=20.Find m.

Answers

Answer:

Slope of the line 'm' = 5

Step-by-step explanation:

Step(i):-

Given that the straight line

              5 x - y = 20

          ⇒ 5x - 20 = y

               y = 5 x - 20

Step(ii):-

The equation of the straight line having to slope 'm'

               y = m x + c

given that the straight line

              y = 5x +20

comparing   y = m x + c

Slope of the line 'm' = 5

find the value of x...

Answers

Answer:

x = 23

Step-by-step explanation:

The 38 degree angle and the (6x +4) angle are supplementary which means both have to add up to 180 degrees. 180 - 38 leaves us with 142. When you plug in 23 to x you get (6(23) + 4) 6 times 23 is 138 and 138 plus 4 is 142. Which gives us our answer of x = 23.

Line R is represented by the following equation: x + y = 2
Which equation completes the system that is satisfied by the solution (1, 1)?
2x + y = 2
4x - 2y = 2
2x - 2y = 2
x + y= 4

Answers

Answer:

4x-2y=2

Step-by-step explanation:

Line R is represented by the following equation:

x+y=2

We need to choose another system of equation of x+y=2

whose solution is (1,1)

The equation must be satisfy the point (1,1)

Option 1: 2x+y = 2

Put x=1 and y=1

2(1)+1 = 3

3 ≠ 2

False

Option 2: 4x-2y=2

Put x=1 and y=1

4(1) - 2(1) = 2

2 = 2

True

Option 3: 2x-2y=2

Put x=1 and y=1

2(1) - 2(1) = 0

0 ≠ 2

False

Option 4: x+y=4

Put x=1 and y=1

1+1 = 2

2 ≠ 4

False

Hence, The system of equation is 4x-2y=2

Step-by-step explanation:

I think we are using the order of PEMDAS. We replace the x with 3. If we simplify this expression this is just 3 to the power of 2 multiplied by 2 then subtracted by 7. So 3^2 = 9 then 9 x 2 = 18. Then 18 minus 7 = 11.
