A vessel is a hollow hemisphere (radius 7 cm) mounted on a hollow cylinder (radius 7 cm, height 13 cm). The inner surface area (cylinder inner curved + hemisphere inner curved) in cm^2 is: (Take π = 22/7) (CSA = curved surface area, TSA = total surface area)

Question

Accepted Answer

880 cm^2. Cyl inner CSA = 2*π*r*h = 2*(22/7)*7*13 = 572. Hemisphere inner CSA = 2*π*r^2 = 2*(22/7)*49 = 308. Total = 572 + 308 = 880 cm^2.

A vessel is a hollow hemisphere (radius 7 cm) mounted on a hollow cylinder (radius 7 cm, height 13 cm). The inner surface area (cylinder inner curved + hemisphere inner curved) in $cm^{2}$ is: (Take π = $\frac{22}{7}$ ) (CSA = curved surface area, TSA = total surface area)
