(C) The diameter of the hollow sphere is $d = 7 \,m$.The radius $r$ of the sphere is given by $r = \frac{d}{2} = \frac{7}{2} = 3.5 \,m$.The area available to the motorcyclist for riding is the surface area of the sphere,which is calculated using the formula $A = 4 \pi r^2$.Substituting the values:$A = 4 	imes \frac{22}{7} 	imes 3.5 	imes 3.5$$A = 4 	imes \frac{22}{7} 	imes \frac{7}{2} 	imes \frac{7}{2}$$A = 4 	imes 22 	imes \frac{7}{4}$$A = 22 	imes 7 = 154 \,m^2$.Thus,the area available for riding is $154 \,m^2$.

The hollow sphere,in which the circus motorcyclist performs his stunts,has a diameter of $7 \,m$. Find the area available to the motorcyclist for riding. (in $,m^2$)
