Question

Find Volume for the cones. Round to the nearest TENTH. (A) Radius of 2 in, and a height of 4 inches (B) Diameter of 6 m, and a height of 3 m (c) Diameter of 5 in, and a height of 10 in

Answer 1

Answer:

A. 16.8 in³

B. 28.3 m³

C. 65.4 in³

Step-by-step explanation:

The volume of a cone is given as:

V = ⅓ * pi * r² * h

Where r = radius of base of cone

h = height of cone

A. Radius = 2 inches, height = 4 inches

It's volume is:

V = ⅓ * pi * 2² * 4

V = 16.8 in³

B. Diameter of 6 m, and a height of 3 m

It's diameter is 6 m, therefore, it's radius is:

r = d / 2 = 6 / 2 = 3 m

It's volume is:

V = ⅓ * pi * 3² * 3

V = 28.3 m³

C. Diameter of 5 in, and a height of 10 in

It's diameter is 5 in, therefore, it's radius is:

r = d / 2 = 5 / 2 = 2.5 m

It's volume is:

V = ⅓ * pi * 2.5² * 10

V = 65.4 in³
