Answer:A combination of variables, numbers, and at least one operation.
Example: x+4
Step-by-step explanation:
In order to not get confused, start by converting cm to m
h=20 cm = 0.2m and r=5cm = 0.05m
The cans are cylinders and we only need the rectangular shape, which is equal to the height x the circumference of the circle (2r(pi)), which you'll have to multiply by 200,000 for the number of cans necessary
your equation is therefore:
A=200,000h(2pi(r))
A=200,000(0.2)(2)(0.05)(pi)
A=4000pi m^2
The answer would be (2,3).
Try sketching it out, it helps :)
The answer is 10x^2+13x+5
I hope that helped
