Question

The perimeter of the following figure is

Answer 1

Answer:

36 cm

Step-by-step explanation:

The figure is a semicircle .

The perimeter = circumference + diameter

Circumference = 1/2 * 2πr

= 1/2*2*22/7*7

= 22 cm

diameter = 7 + 7

=14cm

Therefore ,

total perimeter = 22+ 14

= 36 cm

Hope this helps you :)

Answer 2

Answer:

The perimeter of the figure is 22cm ✔

Step-by-step explanation:

In the given figure, there is a semi-circle having a radius of 7cm.

• Perimeter means the circumstances of the circle.

We know that,

Circumstance of a circle = 2πr

As it is a semi-circle

Circumstance of the semi-circle is given by : πr

• Taking π as 22/7
• r (radius) = 7cm

→ Circumstance of the figure = πr

→ 22/7 • 7

→ 22cm

Therefore, the perimeter of the figure is 22cm ✔
