A Hollow Sphere In Which A Circus Motorcyclist Performs His Stunts, Has An Inner Diameter Of 7m. Find The Area Available To The Motorcyclist For Riding.

Sol:

The inner diameter of the hollow sphere, 2r = 7m

Available area to the motorcyclist for riding = Inner surface area of the sphere

\(\Rightarrow 4\Pi r^{2} = \Pi(2r)^{2}\\\Rightarrow \frac{22}{7} * 7^{2}\\\Rightarrow 3.14 * 49\\\Rightarrow 154.\)

Available area to the motorcyclist for riding =154sq.m.
