Greetings!

Convert both terms into improper fractions:
$=9/1-59/8$
Find the LCM.
$=72/8-59/8$
Simplify.
$=13/8$
Convert to Mixed Number.
$=1 \frac{5}{8}$

The second answer would be correct.

Hope this helps.

Answer:

228 cm²

Step-by-step explanation:

The volume of a cylinder of radius r and height h is given by ...

V = πr²·h

Filling in the given information, we can solve for r:

235.5 = π·r²·12

√(235.5/(12π)) = r ≈ 2.49937 . . . . cm

The area of a cylinder is given by ...

A = 2πr² + 2πrh = 2πr(r +h)

Filling in the radius and height, we can find the area to be ...

A = 2π·2.49937·(2.49937 +12) ≈ 227.698 . . . . cm²

About 228 cm² of aluminum are required to make a typical soda can.
