Question

Rover's cylinder dog bowl has a diameter of 6 inches and a height of 2 inches.Approximately how much water does it hold? Use 3.14 for pi and round your answer to the nearest cubic inch.

Answer 1

volume of the cylindrical dog bowl ≈ 57 inches³(nearest cubic inches)

Explanation:

The amount of water the cylindrical dog bowl can hold is the volume of the cylindrical dog bowl.

volume of a cylinder = πr²h

where

r = radius

h = height

r = 6/2 = 3 inches

h = 2 inches

volume of a cylinder = πr²h

volume of a cylinder = π × 3² × 2

volume of a cylinder = π × 9 × 2

volume of a cylinder = π × 18

volume of a cylinder = 3.14 × 18

volume of the cylindrical dog bowl = 56.52 inches³

volume of the cylindrical dog bowl ≈ 57 inches³

Answer 2

56.5 cubic inch

Explanation:

The Volume of a cylinder can be written as;

V = πr^2 h ......1

Where;

Radius = r

Height = h

Given;

Radius r = diameter/2 = 6/2 = 3 inches

height h = 2 inch

π = 3.14

Substituting the values into the equation 1;

V = 3.14 × 3^2 × 2

V = 56.5 cubic inch

The amount of water it can hold is equal to the volume of the cylinder which is equal to 56.5 cubic inch
