Question

In circle P, BC = 24 ft. What is the length of BAC?

Answer 1

`12\pi \ ft`

Explanation:

we know that

The circumference of a circle is equal to

`C=\pi D`

where

D is the diameter of the circle

In this problem we have

`D=24\ ft`

substitute the value

`C=\pi (24)`

`C=24\pi\ ft`

In this problem BAC represent a semicircle

therefore

To find the length of BAC, divide the circumference by
`2`

`24\pi/2=12\pi \ ft`
