Question

A body moves along a circular path with speed 20m/sec and complete a revolution in 40 sec. Find radius of circular path?

Answer 1

Answer:

Explanation:apply v=radius × 2×pi/time period

Answer 2

Answer:

Speed=20m/s

Time taken=40s

Distance=Speed×Time

=20×40=800m

Distance covered is equal to the circumference of the circular path.

Taking π=3.14 and let Radius be 'r'

=> 2×π×r = 800

=>3.14×r=800÷2

=>3.14×r=400

=>r=400÷3.14

=>r=127.39 m. [Approximately]

Answer:-The radius of the circular path is 127.39m

Hope this answer helps........
