Answer 1

25 x 3.14 x 2 should give you your answer

Answer 2

The distance it will move in two turn is about 78 inch. Option B.

Explanation:

Given,

The diameter of wheel = 25 in

The radius (r) = 12.5 in

To find the distance it will move in two turn.

Formula

The circumference of a circle = 2πr

One turn of a wheel = the length of circumference

So,

The circumference of a circle = 2×3.14×12.5 in = 78.5 in

The distance it will move in two turn is about 78 inch
