A toy is a cone mounted on a hemisphere, both of radius 3.5 cm; the cone's slant height is 12.5 cm. Its total surface area = CSA of cone + CSA of hemisphere. Compute it in cm^2. (Take π = 22/7) (CSA = curved surface area, TSA = total surface area)

Question

Accepted Answer

214.5. CSA cone = 137.5. CSA hemisphere = 2*π*r^2 = 2*(22/7)*12.25 = 2*22*1.75 = 77. Total = 137.5 + 77 = 214.5 cm^2.

A toy is a cone mounted on a hemisphere, both of radius 3.5 cm; the cone's slant height is 12.5 cm. Its total surface area = CSA of cone + CSA of hemisphere. Compute it in $cm^{2}$ . (Take π = $\frac{22}{7}$ ) (CSA = curved surface area, TSA = total surface area)
