Question

Find the perimeter of semicircle whose radius is 14 cm​

Answer 1

Perimeter Of Semicircle by taking the value of π as 3.14= 71.96

Perimeter Of Semicircle by taking the value of π as 22/7 = 72

Step-by-step explanation:

Semicircle

The half of circle from its diameter is called as semicircle.

___________________________

GIVEN

Radius = 14 cm

___________________________

We know that π = 3.14 or 22/7

Perimeter Of Semicircle = πr + 2r

___________________________

Taking the value of π = 3.14

Perimeter Of Semicircle = 3.14 × 14 + 2 × 14

Perimeter Of Semicircle = 3.14 × 14 + 28

Perimeter Of Semicircle = 43.96 + 28

Perimeter Of Semicircle = 71.96

Perimeter Of Semicircle = 71.96

___________________________

Taking the value of π = 22/7

Perimeter Of Semicircle = 22/7 × 14 + 2 × 14

Perimeter Of Semicircle = 22/7 × 14 + 28

Perimeter Of Semicircle = 44 + 28

Perimeter Of Semicircle = 72

Perimeter Of Semicircle = 72
