Answer:
A] 12320cm³
Step-by-step explanation:
Formula for finding the Volume of a cylinder is:
[tex]\pi r^{2} h[/tex]
We have to find the r (radius) from the circumference given, since the value of r is not given.
Circumference = 2[tex]\pi[/tex]r
88 = 2 × [tex]\pi[/tex] × r
r = [tex]\frac{88}{2\pi }[/tex]
r = 14.005...cm
∴ r is 14.01cm.
Now that we have found the value of r, we can proceed to find the volume of the cylinder.
Volume = [tex]\pi r^{2} h[/tex]
= [tex]\pi[/tex] × [tex](14.01)^{2}[/tex] × 20
= [tex]\pi[/tex] × 196.3 × 20
= 12334cm
(Since I've used the whole value of Pi ([tex]\pi[/tex]), my answer didn't specifically match any of the options, but it is closer to the A option, thus 12320cm³ is your answer)
