Answer:

increase = 37.38 cm²

You'd like the first way because it took less effort and less chance of a miscalculation.

Step-by-step explanation:

first way:

(just work with the difference in height)

(0.7 x 8.7 x 2) + (0.7 x 18 x 2) = 37.38 cm²

second way:

old total lateral surface area = (31 x 8.7 x 2) + (31 x 18 x 2) = 1655.4

new total lateral surface area = (31.7 x 8.7 x 2) + (31.7 x 18 x 2) = 1692.78

increase = 1692.78 - 1655.4 = 37.38 cm²

H 24 inches The volume of a cylinder can be found by using the formula v Bh. Which expression can be used to determine B, the ar
Lelechka [254]
The volume a cylinder is v=(area of base)h and since the area of the base is πr², you can write the equation a v=πr²h.  Since the problem wants us to find what be is in the equation of a cylinder as v=Bh, we know that B=πr².  The problem gave us the diameter of the circle so we no the radius is going to be the diameter (24) divided by 2 which equals 12.  therefore B=12²π.

I hope this helps.
