Question

if the diameter of a semicircle is 14cm.find its perimeter?

Answer 1

Perimeter of Semicircle = Pie × r

radius = diameter/ 2 = 14 / 2 = 7 cm

Here , perimeter = pie × 7 = 22/7 × 7 = 22cm

Answer 2

hi frnds

given that diameter= 14cm of semicircle.
perimeter of the a semi circle=?
radius of the semi circle= 7cm
p= πr+d
p=(22÷ 7)× 7+14
p= 22+14
p= 36cm

hope it helps you
