To find the volume of the figure, you can use the formula for the volume of a cylinder:
Volume = π * radius^2 * height
Plugging in the given values:
Volume = 3.14 * (15^2) * 19
Volume = 3.14 * 225 * 19
Volume ≈ 10689.15 cubic inches
To find the surface area of the figure, you can use the formula for the surface area of a cylinder:
Surface Area = (2 * π * radius * height) + (2 * π * radius^2)
Plugging in the given values:
Surface Area = (2 * 3.14 * 15 * 19) + (2 * 3.14 * 15^2)
Surface Area = (6.28 * 285) + (6.28 * 225)
Surface Area = 1791.8 + 1413
Surface Area ≈ 3204.8 square inches
Find the volume and surface area of the figure. Use 3.14 as the approximate value of pie.
Round your answer to the nearest tenth, if necessary.
