Answer:
Option B is correct
the exact volume of the cylinder is given by:
[tex]800 \pi m^3[/tex]
Step-by-step explanation:
Volume of a cylinder(V) is given by:
[tex]V= \pi r^2h[/tex] .....[1]
where, r is the radius and h is the height of the cylinder respectively.
As per the statement:
A cylinder has a radius of 10 m and a height of 8 m
⇒ r= 10 m and h = 8 m
substitute these in [1] we have;
[tex]V = \pi 10^2 \cdot 8 = \pi \cdot 100 \cdot 8 = 800 \pi m^3[/tex]
Therefore, the exact volume of the cylinder is given by:
[tex]800 \pi m^3[/tex]
