A solid wooden toy is a cone (radius 5 cm, slant height 13 cm) standing on a cylinder (radius 5 cm, height 8 cm); the cylinder rests on its base. The total surface area to varnish in cm^2, taking π = 3.14, is closest to: (CSA = curved surface area, TSA = total surface area)

Question

Accepted Answer

533.8 cm^2. Cone CSA = π*r*l = 3.14*5*13 = 204.1. Cyl CSA = 2*π*r*h = 2*3.14*5*8 = 251.2. Bottom circle = π*r^2 = 3.14*25 = 78.5. Total = 204.1 + 251.2 + 78.5 = 533.8 cm^2.

A solid wooden toy is a cone (radius 5 cm, slant height 13 cm) standing on a cylinder (radius 5 cm, height 8 cm); the cylinder rests on its base. The total surface area to varnish in $cm^{2}$ , taking π = 3.14, is closest to: (CSA = curved surface area, TSA = total surface area)
