Answer 2

Answer:

$\tt {\pink{Given:}}$

• Radius = 7cm ⇒ 0.07 m.
• Time = 20 sec.

$\tt {\pink{Solution:}}$

We know that:

$\to \tt {\blue{Circumference \:\: of \:\: circle = 2 \pi r}}$

$\tt \to Circumference = 2 \times \frac{22}{\strikethrough {\cancel{7} } } \times 0.07$

$\to \tt Circumference = 0.44 m.$

We also know that:

$\to \tt {\blue{Velocity \:\: (Circluar \:\: motion) = \frac{Circumference}{time} }}$

$\to \tt Velocity = \frac{0.44}{20}$

$\to \tt Velocity = 0.022m$

HOPE THIS HELPS :D
