Question

find thee area and perimeter of a semi-circle having radius 14cm.

Answer 1

Answer:

Perimeter = 44cm

Step-by-step explanation:

22 ×14

2

= 22 ×2

=44

Answer 2

Solution:

Radius = 14cm

Area of semi-circle = πr^2/2

Area of semi-circle = 22/7 × 14/2

Area of semi-circle = 44/2 = 22cm^2.

$\rule{200pt}{0.1pt}$

Perimeter of circle = πr + 2r

Perimeter of circle = 22/7 × 14 + (2 × 14)

Perimeter of circle = 44 + 28

Perimeter of circle = 72cm.

$\rule{200pt}{0.1pt}$
