Question

The length of a tape required to encircle a circular ring of radius 10 in is in. [Take π = 3.14]

Answer 1

Length of the tape required to encircle a circular ring is equal to the circumference of the circle.

We know:
Circumference of the circle $=2\times \pi \times r$

On putting values, we get:
Circumference of the circle
$=2\times 3.14\times 10$
$=62.8in$

So, length of tape required is 62.8 inch.
