1. Answer:

The radius will be “100.31 m”. A further solving is given below.

Explanation:

The given values are:

Time,

T = 2 minutes

i.e.,

= 120 seconds

Speed,

V = 5.25 m/s

As we know

⇒  $$T=\frac{2 \pi R}{V}$$

then,

⇒  $$R=\frac{TV}{2 \pi}$$

On substituting the given values, we get

⇒      $$=\frac{120\times 5.25}{2\times 3.14}$$

⇒      $$=\frac{630}{6.28}$$

⇒      $$=100.31 \ m$$
