A circular wire of radius 15cm is cut and bent so as to lie along the circumference f a loop of radius 120 cm. write the measure of the angle subtended by it at the centre of the loop.

Text Solution

Verified by Experts

Circumference of the circle=`2pi r`
`2X3.14X15cm`
`94.2cm`
Now,`94.2cm` will be the length of the arc
