Question

Find the perimeter of semi circular disc with a radius of 14 cm​

Answer 1

Answer:

Given that ;

Semi Circular Disc ,

Radius of the Semi Circular Disc ( r ) = 14cm

Perimeter of the Disc ( P ) = ?

Formula :

Perimeter of the Semi Circular Disc,

P = π r + 2 r

P = ( 22 / 7 × 14 ) + ( 2 × 14 )

P = ( 22 × 2 ) + ( 28 )

P = 44 + 28

P = 72cm

Hence;

Perimeter of the Semi Circular Disc,

( P ) = 72cm
