Question

A quarter has a diameter of 2.4. if it makes 8 rotations how far did it roll

Answer 1

7.536

Explanation:

I think it means to find the perimeter and multiply it by 8.

The perimeter of a circle is called the circumference.

C = pi(d)

C = pi(2.4)

C = 7.536

My teacher has us use 3.14 for pi so if your teacher has you use something else just multiply it by 2.4.

Answer 2

Radius = 2.4/2
1.2
circumference = 2piR
= 12/5 pi
Distance = 12/5 pi * 8
= 60.3 units
