The radius of the circle above is 9 in. What is the circumference of the circle? (Use = 3.14.)
A.
508.68 in
B.
56.52 in
C.
254.34 in
D.
28.26 in
C. 56.52 in
The circumference of a circle is calculated using the formula: Circumference = 2πr, where r is the radius of the circle.
Given that the radius is 9 in, substitute this value into the formula:
Circumference = 2 * 3.14 * 9
Circumference = 18 * 3.14
Circumference = 56.52 in
Therefore, the circumference of the circle is 56.52 inches.
