Question

Find circumference of a circle whose area is 200.96 m2

Answer 1

Answer:

50.24 is the circumference

8 is the radius

16 is the diameter

3.14 is pi

Step-by-step explanation:

Answer 2

Answer:

As you known the formula to find the circumference of a circle is 2πr. If you want to find the circumference of a first whose area is 200.96, you have to figure out how to find the area of a circle. The area of a circle is πr². Now you have to sub in the numbers that you know.

A= πr²

200.96 = 3.14 x r²

200.96 = √3.14r²

200.96 ÷ 3.14 = 3.14r ÷ 3.14

64 = r

Since now you have found the radius, you can move on to find the circumference of the circle.

C = 2πr

C = 2(3.14)(64)

C = 401.92m

Therefore, the circumference of a circle whose area is 200.96 m² is 401.92m.
