Question

.....If the area of a semi-circle is 308 square metre. Then find the radius of circle?​

Answer 1

Step-by-step explanation:

A=πr2

Solving forr

r=A

π=308

π≈9.90149m

Answer 2

Answer:

Area of the semi circle = 308 sq m.

Semicircular area =

$\frac{\pi {r}^{2}}{2}$

= 308 sq m

πr^2 = 308 x 2

r ^2 = 308 x 2 x 7 / 22

r^2 = 308 x 7/11

r^2 = 196

r = √196

r = 14 m.
