Question

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

Answer 1

Answer:

The answer is

r =4 ft

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

${r}^{2} = \frac{64}{\pi}$

Find the square root of both sides

$r = \sqrt{ \frac{64}{\pi} }$

r = 4 ft

Hope this helps you

Answer 2

Answer: 8

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.
