38440.53 Is the surface area of the cylinder

Hello!

To find the surface area of a cylinder you use the equation

[tex]SA = 2 \pi rh+ 2 \pi r^{2} [/tex]

SA is surface area
r is radius
h is height

Put in the values you know

[tex]SA = 2 \pi (38)(123) + 2 \pi * 38^{2} [/tex]

Square the number

[tex]SA = 2 \pi (38)(123) + 2 \pi * 1444[/tex]

Multiply 38 and 123

[tex]SA = 2 \pi * 4674 + 2 \pi * 1444[/tex]

Multiply 2 and 4674

[tex]SA = 9348 \pi + 2 \pi * 1444[/tex]

Multiply the 2 and 1444

[tex]SA = 9348 \pi + 2888 \pi [/tex]

Add

[tex]SA = 12236 \pi = 38440.53[/tex]

The answer is 12236 pi or about 38440.53

Hope this helps!
