Answer:
$3
Step-by-step explanation:
8 + 7 = 15
15 - 12 = 3
<em>Note: You missed to add the answer choices, so I am solving the overall procedure to determine the radius of the cylinder so that you could easily figure out the right choice.</em>
Answer:
The radius of the cylinder:
Step-by-step explanation:
The volume of a cylinder is represented by the formula
V=πr²h
here
The radius of the cylinder can be computed using the formula of the volume of a cylinder
V = πr²h
r² = V / πh
Taking square roots

Thus, the formula of the radius of the cylinder.

Therefore, the radius of the cylinder:
Step-by-step explanation:
using Pythagoras theorem
d}^{2} =4}^{2+7}^{2}
d}^{2}=16+49
d}^{2}=65
d}^{2}=√65

d=8.06 or 8
1/3 of 18 is 6
Hope this helps!
