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: 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.

Answer 2

The answer is

r =4 ft

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) = (64)/(\pi)`

Find the square root of both sides

`r = \sqrt{ (64)/(\pi) }`

r = 4 ft

Hope this helps you
