Answer 1

it is given that circumference is 396 m....
to find diameter first we shld find radius....
so by using the formula 2 πr you can get the radius ........
diameter =2*radius..........
hope its useful for u ............

pls mark it as gud ans

Answer 2

Sol'n: circumference of a circular ground = 396m
=> 2πr = 396
=> 2 × 22/7 × r = 396
=> r = 396 × 2 × 7/22
=> r = 252

.°. diameter (d) of the ground = 2r
=> d = 2 × 252
=> d = 504

hope it will help...
