Question

Find the perimeter of given
figure which is a semicircle
including its diameter?
10 cm​

Answer 1

Perimeter of a semi-circle :

= (diameter) + (peremeter of circle) / 2

=+π∗/2
=
d
+
π
∗
d
/
2


=10+3.14∗10/2
=
10
+
3.14
∗
10
/
2


=10+15.7
=
10
+
15.7


=25.7
=
25.7

Answer 2

$\bold{\large{\boxed{\red{\texttt{ANSWER}}}}}$

☆ Diameter of semicircle = 10cm

☆ So , radius of semicircle = 10 /2 = 5cm

We know ,

$\large{\bold{\boxed{ \purple{\sf{{Perimeter \: of \: semicircle \: = \pi {r} }}}}}}$

$\rightarrow{\bold{\sf{ \frac{22}{7} \times {5} }}}$

$\rightarrow{\bold{\sf{15.72 \: cm \: (approx)}}}$

Now as we include diameter :

Total Perimeter = Perimeter of semicircle + Diameter of semicircle

= 15.72 + 10

= 25.72 cm

I hope it helps u dear friend ^_^♡♡
