A cylindrical can containing pieces of fruit is filled to the top with syrup before being sealed. The base of the can has an area of 75 centimeters squared, and the height of the can is 10 cm. If 110 centimeters cubed of syrup is needed to fill the can to the top, which of the following is closest to the total volume of the pieces of fruit in the can?

Explanation

Choice C is correct. The total volume of the cylindrical can is found by multiplying the area of the base of the can, 75 square centimeters, by the height of the can, 10 cm, which yields 750 cubic centimeters. If the syrup needed to fill the can has a volume of 110 cubic centimeters, then the remaining volume for the pieces of
fruit is 750 minus 110, equals 640 cubic centimeters.

Choice A is incorrect because if the fruit had a volume of 7 point 5 cubic centimeters, there would be 750 minus 7 point 5, equals 742 point 5 cubic centimeters of syrup needed to fill the can to the top. Choice B is incorrect because if the fruit had a volume of 185 cubic centimeters, there would be 750 minus 185, equals 565 cubic centimeters of syrup needed to fill the can to the top. Choice D is incorrect because it is the total volume of the can, not just of the pieces of fruit.
