Question

hey..!please solve this problem

Answer 1

radius of a circle=20m
side of the square=40m

area of the remaining area= area of the square - area of the circle.
                              =s²- πr²
                              =40²-22/7×20×20
                              =1600- 22/7×400
                              = 1474.29m

Answer 2

Area

Step-by-step explanation:

Given:

radius of circle (r) = 20m

Side of square park (a) = 40m

Note: circle is in side the park

So, Remaining area = Area of the square park - Area of the circle

Remaining area = (Side x Side) - (πr²)

Remaining area = (40 x 40) - (3.14 × 20 × 20)

Remaining area = (1,600) - (1,256)

Remaining area = 344m²
