Question

find the perimeter of an adjoining figure , which is a semicircule including its diameter ( 10 cm diameter )​

Answer 1

Answer:

perimeter of a circle is 2πr

so semicircle perimeter is 2πr/2

Answer 2

Answer:

Step-by-step explanation:

Diameter of the circle (d)=10cm

Radius of the circle (r)=d/2=10/2=5cm

Total perimeter of the circle (P)=2πr

=31.43cm

Perimeter of the semi-circle= P/2

=15.71cm

Therefore,

Perimeter of the figure= (15.71+10)cm

= 25.71cm
