Question

write the formula to circumference of the semi circle​

Answer 1

$\huge\mathcal{Answer:}$

Perimeter of a Semicircle

The formula for a circle's circumference, C, is C

= 2 * pi * r, where r is, again, the circle's radius. A semicircle is half a circle, however, so we'll need to divide the formula for perimeter by two just like we did the formula for area. The perimeter P = pi * r.

Answer 2

Answer:

formula for perimeter by two just like we did the formula for area. The perimeter P = pi * r.
