The surface area of a cylinder is the area of the top and bottom circle and the side of the cylinder, which is really a rectangle with the circumference of the circle for the length and x for the width.
So the formula is

Plug in r and x into the equation;



which is about
804.25 square units since it is an area.
Hope this helps.
Answer:
A
Step-by-step explanation:
observe
x² + 12x + y² + 10y = –45
add 36 + 25 on both side
x² + 12x + 36 + y² + 10y + 25 = –45 + 36 + 25 = 16
(x + 6)² + (y + 5)² = 16
It depends on what x is equal to. For example, if x = 3, your equation is 3 * 2 + 1 + 3 - 2 = 8.
1.) 7,056 * 41 = 289,296 (apple barrel volume * no. of barrels sold)
5,826 * 41 = 238,866 (cranberry barrel volume * no. of barrels sold)
2.) Subtract cranberry barrel volume from apple barrel volume
289,296 - 238,866 = 50,430 cubic inches
3.) Convert 50,430 cubic inches to liters
50,430 = 826.39 liters or 826.40 liters (rounded off)
4.) Therefore, 826.40 liters is the discrepancy in the shipment volume.
