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:
1. Gained 9 kilos = 
2. 32 steps backward = 
3. Decreased by P5 = 
Step-by-step explanation:
Natural numbers refer to numbers that are used for counting.
Whole numbers include 0 and natural numbers.
An integer is a collection of whole numbers and their negatives.
1. Gained 9 kilos = 
(Gained is denoted by + )
2. 32 steps backward = 
(backward is denoted by - )
3. Decreased by P5 = 
(decrease is denoted by - )
Charges 0.50 per mile with a 5 dollar surcharge. Spending at most 30 dollars, the equation would be:
0.5x+5
30
To find how many miles they can travel/the solution, solve the inequality:

Subtract 5 from both sides.

Divide both sides by 0.5.

They can travel (at most) 50 miles.
Hope this helps :)
