First you need the formula for SA of a cylinder: SA = 2(πr^2) + 2πr*h
(area of the top and bottom circles plus the side)
Then plug your values into the equation and rearrange to make h the subject:
1470.3 = 2π13^2 + 2π*13*h
26πh = 1470.3 - 338π
h = (1470.3 - 338π)/26π
=5.00042...
so h is approximately 5 units :)

<u>Answer:</u>
9c + 10 (see below)
<u>Step-by-step explanation:</u>
To find how much Chris spent on tickets, you can write an expression to represent the situation:
$9c
You can do this to find how much Michael spent as well:
$10m
To find how much Chris and Michael spent combined, add their two costs:
9c + 10
