The expression
r2h represents the volume of a cylinder with radius r and height h. What is the volume, to the nearest tenth of a cubic inch, of the juice can below? Use 3.14 for ℼ.
To find the volume of the juice can, we need to know the values of both the radius (r) and the height (h) of the can. Without this information, we cannot determine the volume.
To find the volume of the juice can, we can use the formula for the volume of a cylinder: V = πr²h.
Given that the radius of the juice can is r = 3 inches and the height is h = 6 inches, we can plug these values into the formula:
V = 3.14 × (3 inches)² × 6 inches.
First, let's calculate the square of the radius: (3 inches)² = 9 square inches.
Next, multiply the square of the radius by π: 9 square inches × 3.14 = 28.26 cubic inches.
Finally, multiply the result by the height: 28.26 cubic inches × 6 inches = 169.56 cubic inches.
Rounded to the nearest tenth of a cubic inch, the volume of the juice can is approximately 169.6 cubic inches.
