Question

B) The circumference of a circular field is 220 m.

(i) Find its diameter and radius.
(ii) Find the cost of paving stones all over it at Rs 25 per sq. m.​

Answer 1

sorry I don't know 2...

But first I can tell....

Explanation:

circumference = 220m

To Find :- It's diameter and it's radius...

Solution:-

circumference of circle = 2*pi*r

pi=22/7

220 = 2*22/7*r

220 = 44r/7

220*7 = 44r

1540 = 44r

r = 1540/44

r = 35m....

d = 35*2

d = 70m...

Hence, Diameter of circular field is 70m and radius is 35m
