Question

(1) Radha travels along a circular path, and when she reaches the spot she started from, she finds
she has covered 352 metres. If she were to walk in a straight line through the center of the circle
and reach the opposite side, how much distance would she have travelled?

Step-by-step explanation:

The distance covered by Radha along the circular path = 352 metres.

Since she traveled a full circle, the distance covered by her is also equal to thecircumference of the circle.

Thus, 2πr = 352, where r is the radius of the circle.

⇒ 2r = 352 / π

Since the diameter of a circle is twice its radius,

⇒ d =$\frac{352}{ \frac{22}{7} }$

⇒ d = 352 × 7/22

⇒d = 112

--------------------------------------------------

If she were to walk in a straight line through the center of the circle and reach the opposite side, the distance would be equal to the diameter of the circle.

Thus, the distance would have been 112 metres.
