Question

find the perimeter of the semi circle of radius 35 cm including the diameter​

Answer 1

Answer:

first you have to find perimeter of circle =

2 ×22/7×35 cm

= 44/7× 35 cm

= 220 cm

then you have to find half of perimeter =

220cm/2

= 110 cm

then find diameter = 35 cm × 2 = 70cm

perimeter = 110cm+ 10 cm = 80 cm

Answer = 80 cm
