Question

find the perimeter of the simicircle of radius 7 cm ?​

Answer 1

Answer:

36 cm

Step-by-step explanation:

If the radius of a semicircle is 7 cm,

the perimeter can be calculated with the help of the formula: Perimeter = (πr + 2r),

where 'r' is the radius and π is equal to 22/7.

On substituting the values we get, Perimeter = (πr + 2r) = (22/7 × 7) + (2 × 7) = 22 + 14 = 36 cm.
