Question

the area of a semicircle is 308mtr square then the radius of circle

Answer 1

area of semicircle = 308 m²
1 π r ² / 2 = 308
22 r²/ 7 = 308 × 2
r²= 308 × 2× 7 /22
r²= 4312 ÷ 22
r² = 196 m²
r =14 m
radius of semicircle is equal to radius of circle
so that radius of circle = 14 m

Answer 2

Answer

Area of circle =πr²

Area of semi circle=1/2πr²

# 308=1/2πr²

308×2/π=r²

r²=196

r=√196

r=14
