A cylinder has a diameter 3cm and a height of 6cm Find the volume of the cylinder.- Use 3.14 for pi. (1 point) Responses 678.24 cubic centimeters 678.24 cubic centimeters 169.56 cubic centimeters 169.56 cubic centimeters 339.12 cubic centimeters 339.12 cubic centimeters 226.08 cubic centimeters
The volume of a cylinder is calculated using the formula V = πr^2h, where r is the radius of the cylinder and h is the height.
Given that the diameter of the cylinder is 3cm, the radius would be half of that, which is 1.5cm.
Now plug the values into the formula:
V = 3.14 * (1.5)^2 * 6
V = 3.14 * 2.25 * 6
V = 42.39 cm^3
So, the correct answer is 169.56 cubic centimeters.
A jar of peanut butter has a height of 16 centimeters and a width of 10 centimeters. Find the volume of the peanut butter jar. Use 3.14 for pi.(1 point) Responses 4,019.2 cubic centimeters 4,019.2 cubic centimeters 1,256 cubic centimeters 1,256 cubic centimeters 5,024 cubic centimeters 5,024 cubic centimeters 2,009.6 cubic centimeters
The volume of a cylinder (or in this case a jar with a cylindrical shape) is calculated using the formula V = πr^2h, where r is the radius of the jar and h is the height.
Given that the width of the jar is 10 cm (which is equivalent to the diameter), the radius is half of that, so the radius would be 5 cm.
Now plug the values into the formula:
V = 3.14 * (5)^2 * 16
V = 3.14 * 25 * 16
V = 1256 cubic centimeters
The correct answer is 1,256 cubic centimeters.
