Find the surface area and volume of the figure.
12 ft diameter
9 ft
Question content area bottom
Part 1
The surface area is
632.4 ft squared. (Round to the nearest tenth as needed.)
Part 2
The volume is
1093.3 ft cubed. (Round to the nearest tenth as needed.)
Surface Area = π × radius × (radius + slant height)
Surface Area = π × 6 × (6 + 9)
Surface Area = π × 6 × 15
Surface Area = 90π
Surface Area ≈ 282.7 ft²
Volume = (1/3) × π × radius² × height
Volume = (1/3) × π × 6² × 9
Volume = (1/3) × π × 36 × 9
Volume = 108π
Volume ≈ 339.3 ft³
