# Calculate the upper bound volume for a cone? watch

1. The diagram shows a cone, radius of base is 8cm, height of cone = 24cm. The question is to calculate the upper bound for the volume of the cone.
I'm aware the volume of a cone is (1/3)(pi)(r^2)h but i don't know what an upper bound is?

Since this is GCSE, I suspect they just want the largest value it could be.

Might be helpful to post the whole question.

Ta.

Yep, they want the largest value it could be, taking into account the accuracy of the measurements given.
5. in the question it probably says "to the nearest cm" at some point
