Question

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

Answer 1

Answer:

radius of semicircle or circle = 14 m

Step-by-step explanation:

area of semicircle = πr²/2

πr²/2 =308

πr² = 308 × 2

πr² = 616

r² = 616 × 7 / 22

r² = 28 × 7

r² = 196

r = √196

r = 14 m

therefore radius of semicircle or circle = 14 m
