D 226.19 in

Answer 1

The area of the circle is":

A = 1017.36 in²

The circumference of the circle is:

C = 113.09 in

Explanation:

Given

r = 18 in

We need to determine the area and circumference of the circle

Using the formula to determine the area

A = πr²

= 3.14 × (18)²

= 3.14 × 324

= 1017.36 in² (Rounded to the nearest 0.01 or the Hundredths Place)

Thus, the area of the circle is":

A = 1017.36 in²

Using the formula to determine the circumference.

C=2πr

= 2 × 3.14 × 18

= 113.09 in

Thus, the circumference of the circle is:

C = 113.09 in
