Answer:
Surface Area of Cone = 200π cm^2
Surface Area of Right Prism = 17.5 ft^2
Step-by-step explanation:
32. We are given a figure of a cone and we are to find its surface area.
We know that the formula for the S.A. of cone is given by:
Surface Area of cone = [tex]\pi r(r+\sqrt{h^2+r^2} )[/tex]
Substituting the given values in the above formula.
Surface Area of cone = [tex]\pi \times 8(8+\sqrt{15^2+8^2} )[/tex] = 200π cm^2
25. We are to find the surface area of a right prism.
Surface Area of Right Prism = Base Perimeter × height + 2(Base Area)
Base Perimeter = 2(4 + 1.5) = 11 ft
Height = 0.5 ft
Base Area = 4 × 1.5 = 6 ft
Substituting these values in the above formula.
Surface Area of Right Prism = 11 × 0.5 + 2(6) = 17.5 ft^2
