Question

A 3 cm x 3 cm rectangle sits inside a circle with radius of 4 cm.

Answer 1

Answer:

41.24cm²

Step-by-step explanation:

See attachment for the figure

First is to find area of rectangle

Given:

Length of rectangle 'l'= 3cm

breadth of rectangle 'b'= 3cm

Area of rectangle= l x b= 3 x 3=> 9cm²

Next is to find the area of the circle

Given:

radius 'r'= 4cm

Area of circle= πr² => π4² =>50.24cm²

Required:

area of the shaded region=?

area of the shaded region=  area of the circle - area of the rectangle

area of the shaded region= 50.24 -9 =>41.24cm²

Therefore, area of the shaded region is 41.24cm²
