Question

Perimeter of semicircle whose diameter is 6m

Answer 1

Answer:

perimeter of semicircle= π×d

=22/7×6 = 18.85m

Answer 2

Answer:

15.43 m

Step-by-step explanation:

Perimeter of a semi-circle = $\frac{1}{2}$ $\pi$ d + d

=   $\frac{1}{2}$ * $\frac{22}{7}$ * 6 + 6

= 9.43 + 6

= 15.43 m

So, the perimeter of the semi-circle is 15.43 m.
