Check the picture below.
[tex]\bf V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ r=12.5\\ h=7 \end{cases}\implies V=\pi (12.5)^2(7) \\\\\\ V=1093.75\pi \implies V\approx 3436.12[/tex]

Answer:
3,434.375
Step-by-step explanation:
First you change the diameter to radius by dividing 25 by 2 which gives you 12.5.
Second the formula for finding the volume of a cylinder is 3.14 x radius squared x height. So all you have to do is plug in the numbers so your equation is...
3.14 x 12.5^2 x 7 = 3,434.375
