The radius r = 15 / 2 = 7.5 m
Volume = pi r^2 h
= 3.14 * 7.5^2 * 3.9
= 688.84 m^2 to nearest hundredth.
Answer: [tex]688.9\text{ m}^3[/tex]
Step-by-step explanation:
Given: The diameter of cylinder = 15 m
Then, Radius = [tex]r=\dfrac{15}{2}=7.5\text{ m}[/tex]
Height =3.9 m
The formula to find the volume of a cylinder is given by :-
[tex]V=\pi r^2 h[/tex]
i.e. [tex]V=(3.14)(7.5)^2 (3.9)[/tex]
[tex]\Rightarrow\ V=688.8375\approx688.9\text{ m}^3[/tex]
Hence, the volume of the cylinder =[tex]688.9\text{ m}^3[/tex]
