Question

Do not round any intermediate computations, and round your answer to the nearest tenth.

Answer 1

For any circle, the circumference i.e. the distance around the circle is 2πr where r is the radius. So there are 2π radius lengths around a circle. There are 2π radians in a circle.

Now, note that the radius is 19 in and the ac length is 10 in. So the central angle measures

`(10)/(19)`
