Question

a wire is in the form of a semi circle of 7cm radius. the length of the wire will

Answer 1

Hi ,

Radius of the semicircle = r = 7cm

Length of the wire = perimeter of

the semicircle + diameter

= πr + 2r

= ( 22/7 ) × 7 cm + ( 2 × 7 )

= 22 cm + 14 cm

= 36 cm

I hope this helps you.

Answer 2

hello users ....

solution:-

we know that :
perimeter of semicircle = πr + 2r 

where, r is the radius of semi circle.

here,
perimeter of semicircle having radius ( r = 7 cm ) 
= π * 7 + 2 * 7
= 22/7 * 7  + 14 
= 22 + 14 
= 36 cm

Hence,
the length of wire in the form of Semi circle = 36 cm Answer
