A metal washer is made by cutting out a circle 13.2 mm in diameter from a larger circle. To the nearest tenth, what is the area of the washer?547.1 mm2972.6 mm260.8 mm2243.3 mm2
Accepted Solution
A:
To find this answer you will subtract the area of the smaller circle from the area of the larger circle.
Area of Big - Area of Small (pi x r^2) Β Β - (pi x r^2) (3.14 x 11^2) - (3.14 x 6.6^2) 379.94 square mm - 136.78 square mm = 243.16 square mm
