Question

If the area of a cone is 30 units squared and its height is 10 units. What is the volume of the cone knowing the equation is v=pi *h* (1/3)*r2

Answer 1

surface area of a cone or area of the base?

Answer 2

Area

Answer 3

um please specify which one

Answer 4

30 units

Answer 5

ug im just going to assume that area means the area of the circular base
in which case

\[A=\pi r^2\]

solve for r

then once you have r, you can solve for the volume

Answer 6

They didn't give me radius

Answer 7

thats why you solve for it...
you have the area

Answer 8

\[r=\sqrt{\frac{A}{\pi}}\]

Answer 9

Can writethe equation you wrote in words

Answer 10

r= square root of Area over pi

Answer 11

Is it 3.1
