Question

perimeter of semi circle​

Answer 1

$\huge\underbrace\mathfrak\red{answer}$

The perimeter of a semicircle is the sum of the half of the circumference of the circle and diameter. As the perimeter of a circle is 2πr or πd. So, the perimeter of a semicircle is 1/2 (πd) + d or πr + 2r, where r is the radius

Answer 2

$\boxed{The \: perimeter \: of \: a \: semicircle }$

1/2 (πd) + d

or

πr + 2r
