A sphere has a diameter of 14 units. What is the volume of the sphere in cubic units? If a cylinder has the same radius as the sphere and a height of 14 units, what is the volume of the cylinder? Use 3.14 for π.
see the attachment for answer:
V≈1436.76 units cube (sphere)
V=πr^2h (cylinder)
r=7
h=14
V≈2155.13 units cube (cylinder)
Answer:
\(\text{Volume of sphere}\approx 1436.03\) cubic units.
\(\text{Volume of cylinder}=2154.04\) cubic units.
Step-by-step explanation:
We have been given that a sphere has a diameter of 14 units. We are asked to find the volume of our given sphere.
\(\text{Volume of sphere}=\frac{4}{3}\pi r^3\), where r represents the radius of sphere.
First of all, let us divide the diameter of sphere by 2 to find the radius of our given sphere.
\(\text{Radius of sphere}=\frac{14}{2}=7\)
\(\text{Volume of sphere}=\frac{4}{3}*3.14*7^3\)
\(\text{Volume of sphere}=\frac{4}{3}*3.14*343\)
\(\text{Volume of sphere}=\frac{4308.08}{3}\)
\(\text{Volume of sphere}=1436.02666\approx 1436.03\)
Therefore, the volume of sphere is 1436.03 cubic units.
\(\text{Volume of cylinder}=\pi r^2h\), where,
r = Radius of cylinder,
h = Height of cylinder.
Upon substituting our given values in above formula we will get,
\(\text{Volume of cylinder}=\pi*7^2*14\)
\(\text{Volume of cylinder}=3.14*49*14\)
\(\text{Volume of cylinder}=2154.04\)
Therefore, the volume of cylinder is 2154.04 cubic units.
