How can i find the volume of a cone 9 radius and 18 height

V = 486, or approx. 1,526.814

Step-by-step explanation:

V = *r²*(h/3)

plug in the numbers: V = * (9)² * (18/3)

simplify: V = * 81 * 6

simplify: V = 486, or approx. 1,526.814

look a the sides they are perpendicular

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
