Question

If the circumference of a circle sheet is 154 m. Find its radius

Answer 1

2πr = 154
r = 154 /2π = 154*7/2*22 = 49/2 = 24.5 m

Answer 2

Given:

Circumference of a circle sheet = 154 m.

To Find:

Radius of the circular sheet.

Solution:

Circumference of a circle sheet = 154 m.

∴ $2\pi r= 154$

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

∴ $r=\frac{154 \times 7}{2 \times 22} = \frac{49}{2} m$

= 24.5 m.

$\boxed{Radius =24.5m}$
