Question

a particle is moving in a circle of diameter 10 m what distance it cover in 2 rounds​

Answer 1

88m

Explanation

Given , Diameter = 10m

Therefore, Radius = 10/2 = 5m

The particle is moving around the circle which means we have to calculate the circumference of the circle

$circumferece \: of \: the \: circle = 2\pi \: r \: \\ \: \: \: \: \: \: \: \: \: \: \: \: \: = 2 \times \frac{22}{7} \times 5 \\ \: \: \: \: \: \: \: \: \: \: \: \ = \frac{308}{7} = 44$

Given the particle covers two rounds.

Thereforethe distance covered by the particle = 2 × 44 = 88m
