To calculate the volume of the spherical chocolate truffle, we can use the formula:

Volume = (4/3) * π * r^3

Plugging in the given radius of 12 mm and using 3.14 as an approximation for π:

Volume = (4/3) * 3.14 * (12)^3
= (4/3) * 3.14 * 1728
= 7238.08 mm³

Therefore, there is approximately 7238.08 mm³ of chocolate in the spherical chocolate truffle.
The volume of a container measures 3,200 in.3 and contains a dozen tennis balls. Each tennis ball has a radius of 2.5 in. How much space in the container is empty? Use 3.14 as an approximation for pi.
To calculate the volume of a single tennis ball, we can use the formula:

Volume = (4/3) * π * r^3

Plugging in the given radius of 2.5 in and using 3.14 as an approximation for π:

Volume = (4/3) * 3.14 * (2.5)^3
= (4/3) * 3.14 * 15.625
= 65.38 in³ (rounded to the hundredth)

Since there are a dozen tennis balls, the total volume occupied by the tennis balls is:

Total volume of tennis balls = 12 * 65.38 in³
= 784.56 in³ (rounded to the hundredth)

To find the space in the container that is empty, we subtract the volume of the tennis balls from the volume of the container:

Empty space = Volume of container - Total volume of tennis balls
= 3200 in³ - 784.56 in³
= 2415.44 in³ (rounded to the hundredth)

Therefore, approximately 2415.44 in³ of space in the container is empty.
Use the formula for the volume of a sphere to find the volume of a basketball that has a diameter of 9.2 inches. Use 3.14 as an approximation for pi and round your answer to the nearest hundredth, if necessary.
The formula for the volume of a sphere is given by:

Volume = (4/3) * π * r^3

Given the diameter of the basketball is 9.2 inches, the radius (r) can be calculated by dividing the diameter by 2:

r = 9.2 inches / 2
= 4.6 inches

Plugging in the given radius of 4.6 inches and using 3.14 as an approximation for π:

Volume = (4/3) * 3.14 * (4.6)^3
= (4/3) * 3.14 * 97.336
= 408.619 in³ (rounded to the nearest hundredth)

Therefore, the volume of the basketball is approximately 408.619 in³.
