Question

What is the circumference of D and the arc length of AB

Answer 1

Given:

There is a figure given in the question as

Required:

We want to find the circumference of D and the arc length of AB

Step-by-step explanation:

Radius of circle is 24 ft

circumference of D is

`C=2\pi r=2*3.14*24=150.72\text{ ft}`

arc length AB is

`A=2\pi r*(105)/(360)=150.72*(105)/(360)=43.96\text{ ft}`

Final answer:

circumference of D is 150.72 ft

arc length AB is 43.96 ft
