A cylinder has a height of 23 m and a volume of 18,488 m³. What is the radius of the cylinder? Round your answer to the nearest whole number. 256 m 50 m 32 m 16 m
h = 23v = 18488
((3.14)r^2)h = v((3.14)r^2)23 = 18488(3.14)r^2 = 804r^2 = 256r = 16
16m
Answer:
Option D - Radius =16 m
Step-by-step explanation:
Given : A cylinder has a height of 23 m and a volume of 18,488 m³.
To find : What is the radius of the cylinder?
Solution : Formula of Volume of the cylinder
\(V=\pi r^2\times h\)
where V is the volume, r is the radius and h is the height.
To find radius the formula became,
\(r=\sqrt{\frac{V}{\pi\times h}}\)
Substitute h=23 m, \(V=18,488 m^3\)and \(\pi =3.14\)
\(r=\sqrt{\frac{18488}{3.14\times 23}}\)
\(r=\sqrt{\frac{18488}{72.22}}\)
\(r=\sqrt{255.99}\)
\(r=15.99\)
Approximately, Radius is 16 m
Therefore,Option D is correct.
