Question

The diameter of a circle is 8 inches. What is the area?
8xin2
16x in 2
32 x in?
64 x in

Answer 1

The answer is 50.24. First, take the diameter and divide it by two (4). Then, multiply it by itself (16). Lastly, multiply it by pi,(3.14).

Answer 2

16π in²

Step-by-step explanation:

Step 1:

We know that area of circle is given by

           A=π * R²  units

Where A= Area

           R= Radius = (Diameter/2)

Step 2:

Here r= 4 inches

Area =  $\pi * 4 *4$

         = $16\pi$ in²
