Find the surface area of a cylinder in terms of pie.
Radius is 9 and height is 20.

522π

Step-by-step explanation:

formula: 2πr^2+2πrh. square= ^2 radius= r height= h

2π(9)^2+2π(9)(20)

162π+2π(180)

162π+360π

result= 522π

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
