Question

find the perimeter of the adjoining figure​

Answer 1

Perimeter Of Semicircle = 25.7 cm

Step-by-step explanation:

GIVEN

Diameter = 10 cm

π = 3.14

___________________________

TO FIND

Perimeter

___________________________

FORMULAS

Radius = Diameter / 2

Diameter = 2 × Radius

Perimeter Of Semicircle = ½ × ( π × d ) + d

or

Perimeter Of Semicircle = π × r + 2 × r

Area Of Semicircle = ½ × ( π × r² )

Perimeter Of Circle = 2 × π × r

Area Of Circle = π × r²

___________________________

We know that,

Perimeter Of Semicircle = ½ × ( π × d ) + d

Perimeter Of Semicircle = ½ × ( 3.14 × 10 ) + 10

Perimeter Of Semicircle = ½ × 31.4 + 10

Perimeter Of Semicircle = 15.7 + 10

Perimeter Of Semicircle = 25.7

Perimeter Of Semicircle = 25.7 cm
