Question

Find The perimeter of the adjoining figure, Which is a semicircle including its diameter.

Answer with explanation please​

Answer 1

Answer:

From the question it is given that,

Diameter of semi-circle = 10 cm

We know that, radius (r) = d/2

= 10/2

= 5 cm

Then,

Circumference of the semi-circle = πr

= (22/7) × 5

= 110/7

= 15.71 cm

Now,

Perimeter of the given figure = Circumference of the semi-circle + semi-circle diameter

= 15.71 + 10

= 25.71 cm
