Question

OR
The circumference of a circular sheet is 154 m. Find is radius, also find area of the sheet.​

Answer 1

Answer:

radius= 24.5 m, area= 1886.5 m²

Step-by-step explanation:

Circumference= 2πr= 154

2 x 22/7 x r = 154

r= 154 x 7/22 x 1/2= 49/2 m

Area= πr²

= 22/7 x 49/2 x 49/2 = 1886.5 m²

Answer 2

Answer:

circumference of a circular sheet = 2(pie)r

or, 154 = 2(pie)r where pie =22/7

or, 154×7/22×2 = r

r = 24.5m.

Now,

Area of circular sheet = (pie)r²

=22/7×(24.5)²

=1886.5m²
