Answer 1

Question :-

find the diameter of the circle whose area is 1964.5 sq.m

Required Answer :-

Area of a circle = 1964.5 sq.m - (given)

Area of circle = π r^2

1964.5 = 22/7 x r^2

1964.5 x 7 = 22 x r^2

13751.5 = 22 x r^2

13751.5/22 = r^2

625.0 = r^2

625 = r^2

√625 = r

r = 25 m

Now, we know that

radius = 1/2 diameter

25 = 1/2 x d

25 x 2 = d

50 = d

d = 50 m
