Question

What is the radius of of a circle with a circumference of 18π ft?
A. 6 ft
B. 9 ft
C. 18 ft
D. 9π ft
Is It B Or D?

Answer 1

Is It B Or D?

Answer 2

Circumference = 2 * PI * radius, So,
18 PI = 2 * PI * radius
radius = 18 PI / (2* PI)
I think you can solve it from there.

Answer 3

So Its Not B Or D >.<

Answer 4

Calculate 18 * PI / 2 * PI

Answer 5

Or 18 * 3.14 / 2 * 3.14

Answer 6

88.7364?

Answer 7

Okay solve (18/2) * (PI/PI)
