Answer:
703.7cm²
Step-by-step explanation:
Since we must not count the top and bottom 2cm,
- The height of the label is (20-2-2) = 20 - 4 = 16cm
- Finding the curved surface area of a cylinder: 2πrh
where r = radius and h = height.
- Since the diameter is 14cm, the radius is 14/2 = 7cm
- Substituting 'r=7' & 'h=16' into the curved surface area of a cylinder formula:
2π(7)(16)
= (14)(16)π
= 224π
= 703.716754404cm²
≈ 703.7cm²

The equation system is
1.25x+0.75 (92-x)=87.5
Solve for x
1.25x+69-0.75x=87.5
0.5x+69=87.5
0.5x=87.5-69
0.5x=18.5
X=18.5÷0.5
X=37 units of candy bras
(92-37)=55 units of water bottles
Mr's Powell's class sold more items
Let's look which class earned more
Mr's Powell's class earned
55×0.75=41.25
Mr's Rodman's class earned
37×1.25=46.25
So from above
Mr's Rodman's class earned more
Hope it helps!
In number form that would be 3,167
p.s.may i have the brainliest answer?
You do this 35*x=21. and x is the percent. x=0.6. 0.6 is 60 percent. So 21 is 60 percent less than 35.
