A circle has a radius of 8.5yd. A sector of the circle has a central angle of 0.9 radians. Find the area of the sector.

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

Solution

Area of sector

(n/360)pi r²

0.9 radians=51.5662 degree

(51.5662/360)pi *8.5² = 32.5 square yds
