Answer:
380.8cm³
Step-by-step explanation:
Volume of a Cylinder is: [tex]V=\pi r^2h[/tex]
'r' is the radius.
'h' is the height.
We are given a height of 9.9 cm and a diameter of 7cm.
The radius is half the diameter.
Divide 7 by 2:
[tex]7/2=3.5[/tex]
The radius is 3.5 cm.
Solve for The Volume (Using 3.14 for pi):
[tex]V=3.14*3.5^2*9.9\\\rightarrow3.5^2=12.25\\V=3.14 * 12.25 * 9.9\\V=38.465 * 9.9\\\boxed {V=380.8035}[/tex]
380.8035 ≈ 380.8
The volume of the cylinder should be 380.8cm³.
