The area of circle Z is 64x ft?.

What is the value of?

r = 4 ft

r = 8 ft

r = 16 ft

r = 32 ft

4 ft

Step-by-step explanation:

To calculate the area of a circle is πr^2

π means 3.142

r means?

Area of the circle is given as 64

So let solve the question

3.142*r^2=60

3.142r^2=60

Divide both sides by 3.142

r^2=19.096

Square root of both sides

r=4.37~4

Therefore the final answer for r is 4 ft
