The area of circle Z is 64 ft^2. What is the value of r?
Or= 4 ft
O r= 8 ft
O r= 16 ft
O = 32 ft

The answer is

Step-by-step explanation:

Area of a circle is given by πr²

Where r is the radius

From the question

Area = 64 ft²

So the radius is

64 = πr²

Divide both sides by π

Find the square root of both sides

r = 4 ft

Hope this helps you

The answer is 8 not 4.5 or 4

Step-by-step explanation: It's not just "64" its 64pi. when you posted the question your device could not put the pi symbol so people were thinking that it was just 64.
