Answer: 490

Step-by-step explanation:By rounding up the numbers to the nearest whole, the volume of the cone is 490 .

Given the following data:

Radius of cone = 7.2 cm

Height of cone = 9.7 cm.

To work out an estimate for the volume of the cone:

First of all, we would round up the numbers to the nearest whole:

Radius = 7.2 = 7 cm

Height = 9.7 = 10 cm

Pie = 3.142 = 3.

Mathematically, the volume of a cone is given by the formula:

Substituting the given parameters into the formula, we have;

Volume = 490
