Question

if the circumference of a circular sheet is 154 metre,find its radius .also find the area of the sheet. take pai =22/7​

Answer 1

Answer:

Circumference = 2πr =154 m

=> 2 x (22/7) x r = 154

=> r = 24.5m

Area = πr^2 = (22/7) x r^2

=> (22/7) x (24.5)^2 = 1886.5 m2

4.5

Answer 2

HERE YOU GO~

_________________

GIVEN~

2πr (Circumference) of circle = 154m

π = 22/7

_______________________________________

TO FIND~

radius = ?

area = ?

_______________________________________

SOLUTION~

2πr = 154m

2 × 22/7 × r = 154m

22r = 154 × 7/2

r = 77 × 7 / 22

r = 7 × 7/2

r = 49/2

THEREFORE [r = 24.5 m].

NOW ~

Area of circular sheet = πr^2

= 22/7 × 24.5 × 24.5

= 1886.5 m^2.

HOPE THIS HELPS YOU.....

THANKS......
