Question

if the diameter of a semicircular protractor is 14cm then find its perimeter

Answer 1

Hiii friend,

Diameter of semicircle protractor = 14 cm

Radius = D/2 = 14/2 => 7 cm

Perimeter of semicircle protractor = (πR+2R) =

=>22/7 × 7 + 2 × 7

=> 22 + 14 => 36 m



HOPE IT WILL HELP YOU...... :-)

Answer 2

Hiii!!!

Here's Ur answer..

Given diameter of the semi circular protractor = 14cm

Perimeter of semi circular protractor = πd/2 + d

= ( 22/7 × 14 × 1/2 ) + 14

= ( 22 × 2 × 1/2 ) + 14

= 22 + 14

= 36cm

Hope this helps..!!
