Question

Find the perimeter of semicircle whose radius is 14.7 cm

Answer 1

Step-by-step explanation:

Hey... I think this can be ur answer!!

___________________________

Perimeter of semicircle = pie r

So,

Perimeter = 22/7 * 14 = 22*2 = 44cm...

SO when circle is cut into half than diameter is also included

Now,

Final perimeter of semicircle = 28 + 44 = 72cm

hope this will help you nd make sure to mark as Barinlist dear

Answer 2

$\huge{\underline{\underline{\purple{\mathfrak{♡Ãnswër♡}}}}}$

circumference of semi circle= πr

here r = 14.7cm

so,

3.14×14.7

$\huge{ \boxed{46.158 \: cm}}$

final perimeter = diameter+ 46.158cm

diameter=2×14.7

=29.4

29.4+46.158

75.558 cm
