Question

Instructions: Find the surface area of the figure below. Round your answers to the nearest tenth, if necessary.

Answer 1

The surface area of the cone is calculated to the nearest tenth as: 173.4 cm².

What is the Surface Area of a Cone?

Surface area of a cone = πr(r + l),

Given the following:

• Radius (r) = 4 cm
• Slant height (l) = 9.8 cm

Plug in the values

Surface area of the cone = π × 4(4 + 9.8)

Surface area of the cone = 173.4 cm²
