Question

If the circumference of a circular sheet is 154 m, find its radius. Also find the area of the sheet. (Take π = 22/7)​

Answer 1

Answer:

Given that circumference of circle = 154 m  i.e 2 π r = 154 ⇒ r = 154 / 2 π ⇒ r = 154 x 7 / 2 x 22. ⇒ r = 49 / 2  = 24.5 m ∴ radiu of circle = 24.5 m Area of circle A = π r2  A = π x 49 / 2 x 49 / 2  = 3773 / 2 = 1886.5 m2 .

Answer 2

Answer:

Radius= 24.5 m

Area= 1886.5 m²
