The correct answer would be A 355.5
If you take the base number of 35.55 and multiply is by 100 it should be 3,555 cm not 355.5 cm
Exact Surface Area = 378pi
Approximate Surface Area = 1186.92
The approximate surface area uses pi = 3.14
The units are cm^2 or "square cm".
=========================================================
Work Shown:
SA = surface area of cylinder
SA = 2*pi*r^2 + 2*pi*r*h
SA = 2*pi*7^2 + 2*pi*7*20
SA = 2*pi*49 + 2*pi*140
SA = 2*49*pi + 2*140*pi
SA = 98pi + 280pi
SA = 378pi ..... exact surface area
SA = 378*3.14
SA = 1186.92 ..... approximate surface area

Side note: The diameter 14 cuts in half to get the radius r = 7
Is this 13 and 34 ? or 1,3,3,4?
D. 24 oz because 1cup is equal to 8 fluid ounces so in order to make 3 cups you have to multiply 3 by 8 which equals to 24
