Question

Find the volume of the following cone. Round your answer to the nearest integer.

Answer 1

Answer:

754

Explanation:

right triangle a² + b² = c²

9² + b² = 13²

81 + b² = 169

b² = 169 - 81

b² = 80

b =
`√(80)`

`V = (1)/(3) \pi r^2h`

`V = (1)/(3) \pi (√(80) )^2 (9)`

`V = 3\pi (80)`

`V = 240\pi`

Using π = 3.14 Using calculator value of π

V = 753.6 V = 753.9822369
