What is the area of a sector with a central angle of 3pi/5 radians and a diameter of 21.2cm
Elenna [48]
Answer: 105.84 cm^2

To find the answer, first you have to start by finding the percent of the circle in the sector. Convert the radians given to 108 degrees. 108 out of 360 is 30%. 

Now, find the area of the circle. It's pi x r^2, so the area is 352.810.

Multiply this by 30% to find our area of 105.84 cm^2
