Based on the cone shown, which statements are correct?

a
The equation \large h=\frac{3V}{\pi\left\langle3^2\right\rangle} can be used to find the height of the cone

b
If the height of the cone is 20 cm, then the volume of the cone is approximately 289 cm^3
c
If the volume is 47 cm^3, then the height of the cone is approximately 5 cm
d
If the height of the cone is 10 cm, then the volume of the cone is approximately 74 cm^3
e
The equation: \large V=\frac{1}{3}\pi\left\langle3^2\right\rangle h can be used to find the volume of the cone.

Correct statements: a, c, d, and e.

Interesting that the robot tutor gave an answer, which makes no sense,

to a question which would not possibly be answered, since diagrams
can't be shown on this webpage.
