Question

if area of the circle is 36.5cmsquare then the diameter of the circle is

Answer 1

area of circle=36.5 cm square

pi r square = 36.5

r square =36.5/pi

r=√36.5/pi

diameter =2r=2√36.5/pi


hey mate pls mark my answer as brainliest and follow me if it helps

Answer 2

Area of circle = pi r sq.

Area of circle = 36.5 (given )

Pi r sq = 36.5

22/7 × r ×r =36.5

r×r = 36.5 × 7/22

r sq =11.61

r = under root 11.61

r = 3.40

We know that,

D = 2r

D = 2× 3.40

D = 6.8

Hence the diameter will be 6.8

Hope it will help you.
