2. Determine the volume of the figure that has a radius of 2 feet. Round your answer to the nearest tenth of a
cubic foot.
Answer:
-3 ft
-2 ft
10 ft

Answer 1

Answer: 138.23 ft³

Explanation:

V = V of Cylinder + V of Cone

V of Cylinder = πr^2h

V of Cylinder = (2)^2 x 10 x π

V of Cylinder = 40π

V of Cone = πr^2(h/3)

V of Cone = π x (2)^2 x 3/3

V of Cone = π x 4 x 1

V of Cone = 4π

Total V = 40π + 4π

Total V = 138.23 ft³

Answer 2

Explanation:

The volume of a cone is given by the formula (1/3)πr^2h, where r is the radius of the base and h is the height. So, the volume of the cone is:

V_cone = (1/3)π(2 ft)^2(3 ft)

V_cone = (4/3)π ft^3

The volume of a cylinder is given by the formula πr^2h, where r is the radius of the base and h is the height. So, the volume of the cylinder is:

V_cylinder = π(2 ft)^2(10 ft)

V_cylinder = 40π ft^3

To find the total volume, we add the volumes of the cone and cylinder:

V_total = V_cone + V_cylinder

V_total = (4/3)π + 40π

V_total = 133.2 ft^3

Rounding off the answer to the nearest tenth of a cubic foot, the total volume is approximately 133.2 ft^3.
