Question

What is the volume of a cone if the height is 18 and the radius is 4

Answer 1

301.59289

Explanation:

radius(r) = 4

height (h) = 18

we know,

volume of cone =

`\pi \: {r \:}^(2) (h)/(3)`

`(22)/(7) \: * {4}^(2) \: (18)/(3)`

=301.59289

Answer 2

V = 302

Explanation:

Here, we have Radius(r)=4and Height(h)=18(Given)

l^2=r^2+h^2

l^2=42+182

l^2=340

l=18

Volume= πr2h/3

= 3.14159⋅42⋅18/3

= 302
