Question

find the radius of semi circle whose perimeter is given as 22 cm​

Answer 1

Given:-

• Perimeter of Semi- circle is 22 cm.

To Find-

• Radius of semi-circle

Solution-

Put the perimeter in Formula

$= > 22 = \frac{22}{7} r + 2r$

$= > \frac{22 \times 7}{22} = 3r$

$= > 7 = 3r$

$=> \: r = \frac{7}{3}$

Thus , Radius of semi-circle is 7/3 cm
