The exact surface area is 150.8 and the exact volume is 141.37.
To answer this I used the formula for surface are for a right cylinder which is. 2•3.14•r•h+2•3.14•r^2 (^2 means to the power of 2) r=radius and h=height. When you replace the r’s and the h’s with the radius and height it’ll look like this. 2•3.14•3•5+2•3.14•3^2. For the power of 2 (^2) we basically just do 3•3. But when you put that into a calculator it gives you 150.8.
To find the volume use the formula 3.14•r^2•h when you replace the r’s and the h’s with the height and the radius it’ll look like this. 3.14•3^2•5. When put into the calculator it gives you 141.37.
The examples and solutions to the functions are illustrated below based on the information given.
<h3>How to illustrate the functions?</h3>
1st example: The cost of a bag of rice is $100 and subsequent bags cost $95. Illustrate. the function to calculate the cost for p bags of rice.
The function will be:
C = 100 + (95 × p)
C = 100 + 95p
<u>2nd example:</u><u> </u>The cost of a pen is $5. Find the cost of s pens.
The function will be:
C = 5 × p
C = 5p
<u>3rd example</u>: Calculate the total amount for m tickets if each ticket is $20.
The function will be;
C = 20 × m
C = 20m
<u>4th example:</u> Bon bought g mangoes at $2 each and d oranges at $3.40 each. Calculate the total cost.
C = (2 × g) + (3.40 × d)
C = 2g + 3.4d
<u>5</u><u>t</u><u>h</u><u> </u><u>example</u><u>:</u><u> </u>The average age of k number of boys is 7. Find their total age.
The function will be:
a = (7 × k)
a = 7k

It means to most likely isolate the variable and you should have something like w= or a number =w
Answer:
60 km/hr
Step-by-step explanation:
Speed = distance / time
Speed = 360 km / 6 hr
Speed = 60 km/hr
