Question

What is the approximate are of the shaded region's?

Answer 1

Calculate the area of the squares and the area of the circles, then subtract the area of the circle from the square.

Square with 14 m side:

Area of square = 14 x 14 = 196 square m.

Area of circle inside: 3.14 x 7^2 = 3.14 x 49 = 153.86 square m.

Area of shaded region: 196 - 153.86 = 42.14 square m.

Square with 8 m side:

Area of square: 8 x 8 = 64 square m.

Area of circle: 3.14 x 4^2 = 3.14 x 16 = 50.24 square m.

Area of shaded region: 64 - 50.24 = 13.76 square m.
