Question

if circumference of a circular sheet is 154m, find its radius and area(take π 22/7)​

Answer 1

Answer:

Circumference of circle

$= 2\pi r$

$154 = 2 \times \frac{22}{7} \times r$

Therefore,

$r = \frac{154 \times 7}{22 \times 2}$

$r = \frac{49}{2}$

r= 24.5m

Area = π × r^2

= 22/7 × 24.5 × 24.5

= 1886.5m^2
