Answer:
Area = 87.9646 sq. units from A = 28*π sq. units.
However I cannot see this in your answer list, since the numbers look all jumbled. Choice A. looks close to it, since there is a 28...
Step-by-step explanation:
We have a cylinder with height h = 5
radius = 2
We want the surface area of this cylinder.
A = (circumference)*h + 2*(pi)*r^2
A = ( 4*π)*5 + 2*π*(2^2)
A = 20π + 8π = 28 π square units
A = 87.9646 sq.. units
The correct answer here is A. (3, 21) because when you graph these equations, you will find the lines intersect at this point and only this point.
Answer:
D 8 hours
Step-by-step explanation:
