<h3>Answer: 75.36 square feet</h3>

Your teacher may want you to type the number only.

==========================================================

Work Shown:

SA = surface area of a cylinder

SA = 2*pi*r^2 + 2*pi*r*h

SA = 2*3.14*2^2 + 2*3.14*2*4

SA = 75.36

The surface area is roughly 75.36 square feet.

Which is more 45g or 45ml?

MatroZZZ [7]

For water 1 gram = 1 ml.

This means 45 grams are equal to 45 ml's.

Neither one is greater than the other one as they are equal.

The problem doesn't state what is being measured, so the answer could be different depending on the density of the product being measured.
