Question

What is the surface area of the composite figure? (Use 3.14 for π .)

Answer 1

so, the Area of a sphere is going be = 4πr2 the area of a cylinder will be 2πr(h+r)

so your total area will be half of the sphere's total area that is 4πr^2/2⟹2π8^2 PLUS the cylinder's 2π8(7+8)

2π82+2π(8)(7)+π82

I hope i help
