Answer:
Cone 1 = 29.32mi || Cone 2 = 1526.81
Step-by-step explanation:
Step 1) Apply formula (volume of cone)
V= 1/3 * π * r^2 * h [OR] V= π * r^2 * h/3
Step 2) Insert numbers. (cone 1)
V= π * 2^2 * 7/3
Step 3) Insert numbers. (cone 2)
V= π * 9^2 * 18/3 (r=9 because r=1/2 base diameter of circle, 18/2=9)
Step 4) Plug and solve.
Step 5) CHECK YOUR ANSWER BEFORE SUBMISSION. Do it a few times just to make sure it checks out, and then continue!
