19. The circumference of a circular part of a
cylinder is 88cm. Its height is 20cm.
Calculate the volume of the cylinder
A. 12320cm
B. 30.8cm
C. 3080cm
D. 1760cm

A] 12320cm³

Step-by-step explanation:

Formula for finding the Volume of a cylinder is:

We have to find the r (radius) from the circumference given, since the value of r is not given.

Circumference = 2r

88 = 2 × × r

r =

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 =

= × × 20

= × 196.3 × 20

= 12334cm

(Since I've used the whole value of Pi (), my answer didn't specifically match any of the options, but it is closer to the A option, thus 12320cm³ is your answer)
