Answer 1

@Vocaloid

Answer 2

I didn't get that answer.
How did you do it?

Answer 3

I got it from looking at the 3 in. on the circle.

My other answer was B.

Answer 4

You need to use a formula and calculate the arc length.
The 3 inches in the figure is the radius. The radius is not the arc length.

Answer 5

The arc length is a part of the entire circumference of the circle.
This circle has a radius of 3 in.
What is the circumference of the circle?

@Vocaloid Can you help me please?

@mathstudent55 The circumference would be 9.42

Answer 8

Use:

\(C = 2 \pi r = 2 \times 3.14159 \times 3 ~in. = \)

Answer 9

You forgot the 2 in the formula for the circumference.
