Question

The perimeter of a semicircle ( including its diameter) of radius 7cm is

Answer 1

$<i>$Given -

Radius = 7 cm

Diameter = 2 × radius

= 2 × 7 = 14 cm

Perimeter of semicircle = πr + Diameter

= 22 / 7 × 7 + 14

= 22 + 14

= 36 cm

Answer 2

We know that the Perimeter of a circle is - πr + D

Where, r is radius and D is perimeter.

We have been given:-

r = 7 cm

So, D = 7 x 2 = 14 cm

Now, substitute these values in the formula:-

= ( $\frac{22}{7}$ x 7 ) + 14

= 22 + 14

= 36 cm

So, the answer is 36 cm !
