This is the concept of areas of solid materials; the surface area of the cylinder whose radius is 2.5 cm and lateral area is 20 pi cm^2 will be: Surface area of cylinder is given by:
SA=(area of cyclic sides)+(lateral area)
SA=2πr^2+πrl
Area of the cyclic sides will be:
Area=2πr^2
=2*π*2.5^2
=12.5π cm^2
The lateral area is given by:
Area=20π cm^2
Therefore the surface area of cylinder will be:
SA=(12.5π+20π) cm^2
SA=32.5π cm^2
The answer is 32.5π cm^2

Answer:
A. -2, 1
Step-by-step explanation:
Observe the chart and see where the f(x) and g(x) intersect.
When x=-2, f(-2)=g=(-2) and when x=1, f(1)=g=(1).
Answer:
The probability of a person going to work by car is 48
And the probability of different way is 52
Step-by-step explanation:
As it's represented in the table above, there are 48 percent employees use cars as their transportation to work, and to find the rest sum all the probability of other transportation together which will give you 52 percent.
