Question

The circumference of a circle exceeds its radius by 37 cm find the diameter of the circle use pie =22/7

Answer 1

Answer:

Radius (r) =37 cm

pie = 22\7

diameter (d)=?

Now

Area = pie r^2

= 22 / 7 × ( 37 ) ^2

= 22 / 7 × 1369

= 4302.57 ans

Again,

Area = pie d^2\4

or,4301.57=22\7 × ( d ) ^2\4

or, 30118 \22=(d)^2\4

or,1369=d^2\4

or , 5476 =d^2

or ,root under 5476=d

or, d=74

Therefore, diameter is 74...
