Question

The cone of the volcano has a height of 414 meters and a diameter of 416 meters. Find the volume of the cone. Round your answer to the nearest hundred thousand. Use 3.14 for 1. The volume of the cone is about m3.

Answer 1

Volume of a cone is given by;

`V=(1)/(3)\pi^{}r^3h`

From the queston,

h = 414

diameter = 416, this implies r = d/2 = 416/2 = 208

π = 3.14

substitute the values into the formula

`V=(1)/(3)*3.14\text{ }*208^2*414`
`=18747156.48`
`\approx18700000m^3`
