The hollow sphere, in which the circus motor cyclist performs his stunts, has a diameter of 7 m. Find the area available to the motorcyclist for riding.
Surface area of a sphere = 4πr2
Given, hollow sphere, in which the circus motor cyclist performs his stunts, has a diameter of 7 m
Area available to the motorcyclist for riding = 4 × (22/7) × 3.52 = 154 m2
