Question

Calculate the area of a semicircle of radius 14cm.

Answer 1

Answer:

307.867 cm²

Step-by-step explanation:

Area of semicircle=πr²/2

r=14 cm

area=3.1415*14*14/2

       =307.867 cm²

       =3.079*10∧-2 m²

Answer 2

Step-by-step explanation:

radius =14cm

we know that,

area of semi-circle=1/2*πr^2 [π=22/7]

so,

1/2*22/7*14*14

11*2*14/1

308/1

308cm^3
