Question

Measure of an arc of a circle is 80 cm and its radius is 18 cm. Find the length of the arc. (π = 3.14 )

Answer 1

Hi ,

It is given that ,

I think it may be measure of an arc ( x ) = 80°

Radius of the circle ( r ) = 18 cm

π = 3.14

Length of the arc ( l ) = ( x/360 ) × 2πr

l = ( 80/360 ) × 2 × 3.14 × 18

l = 25.12 cm

I hope this helps you.
