Question

Find the perimeter of a semicircle whose diameter is 62m

Answer 1

Step-by-step explanation:

Given:-

Diameter of the semi-circle=62 cm.

π=$\frac{22}{7}$

To Find:-

The perimeter of the semi-circle.

Formula Applied:-

Perimeter of a semi-circle=πr

Solution:-

Diameter of semi-circle=$2\times Radius$

$62=2\times Radius$

$Radius=\frac{62}{2}\: m$

$Radius=31\:m$

Perimeter of the semi-circle=πr

$Perimeter\:of\:the\:semi-circle=\frac{22}{7}\times31$

$\large\boxed {Perimeter\:of\:the\:semi-circle=\frac{682}{7}\:m}$
