Question

Find the circumference off a semicircular shape on a line of length 14 cm​

Answer 1

The answer for your question is

The formula to find the circumference of a semicircle shape is pi×r

which is 22/7×7

So the circumference is 22cm

Answer 2

$\large\mathcal{ANSWER}$

Perimeter of the semicircle is obtained using the formula r ( $\bf\pi$ + 2 ).

Radius r = 14 cm

So, perimeter = 14 ( $\bf\pi$ + 2 )..... where $\bf\pi$ = $\bf\frac{22}{7}$

= 2 ( 22 + 14 ) = 44 + 28 = 72 cm

Hence, the answer is 72 cm.
