The total surface area of the can of coke is 641.143 cm².
<h3>What is the total surface area of the can?</h3>
A can of coke has the shape of a cylinder. A cylinder is a three-dimensional object that is made up of a prism and two circular bases. The total surface area of a closed cylinder can be determined by adding the area of all its faces.
Total surface area of the closed cylinder = 2πr(r + h)
Where:
- r = radius = 6cm
- h = height = 11 cm
- r = pi = 22 / 7
Total surface area of the closed cylinder = (2 x 22/7 x 6) x (6 + 11)
(264 / 7) x (17)
37.714 x 17 = 641.143 cm²

50m and 30m
7.5 m and 4.5 m
Step-by-step explanation:
Each of these polygons all have a divisible with each other.
30 / 6 = 5
50/ 10 = 5
7.5/ 2.5= 3
4.5/ 1.5= 3
Answer:
None
