Question

What's the area of a sector of a circle that has a diameter of 10 in. if the length of the arc is 10 in.?

Answer 1

Answer:

25 SQ IN. FOR PENN

Step-by-step explanation:

Answer 2

"The diameter is 10, therefore radius = 5. If arc length = 10, then angle = 10/5 = 2 radians 2 radians = 2/2pi = 1/pi of a complete circle. 
Area of circle = pi * r^2 = 25pi. 
Area of sector = angle * area of circle = 1/pi * 25pi = 25"
