Answer:
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
