Question

A circle with radius of 2 cm sits inside a 11 cm x 12cm rectangle. What is the area of the shaded region

Answer 1

Area of shaded region = 119.44 cm²

Explanation:

Area of circle = πr²

= 3.14 × 2²

= 3.14 × 2 ×2

= 12.56 cm²

Area of rectangle = length × breadth

= 11cm × 12cm

= 132 cm²

Area of shaded region = Area of rectangle - Area of circle

= (132 - 12.56) cm²

= 119.44 cm²
