(A) Given radius $r = 14\, cm$.$1$. The curved surface area $(CSA)$ of a hemisphere is given by the formula $2\pi r^{2}$.$CSA = 2 	imes \frac{22}{7} 	imes 14 	imes 14 = 2 	imes 22 	imes 2 	imes 14 = 1232\, cm^{2}$.$2$. The total surface area $(TSA)$ of a hemisphere is given by the formula $3\pi r^{2}$.$TSA = 3 	imes \frac{22}{7} 	imes 14 	imes 14 = 3 	imes 22 	imes 2 	imes 14 = 1848\, cm^{2}$.Thus,the curved surface area is $1232\, cm^{2}$ and the total surface area is $1848\, cm^{2}$.

Find the curved surface area and the total surface area of a hemisphere with a radius of $14\, cm$.
