# Find the Surface Area cylinder (8.5)(1.5) h=8.5r=1.5
The surface area of a cylinder is equal to the sum of the areas of the bases each having an area of π⋅r2, plus the area of the side. The area of the side is equal to the area of a rectangle with length 2πr (the circumference of the base) times the height.
Substitute the values of the radius r=1.5 and height h=8.5 into the formula. Pi π is approximately equal to 3.14.
2(π)(1.5)2+2(π)(1.5)(8.5)
Simplify each term.
Raise 1.5 to the power of 2.
2π⋅2.25+2(π)(1.5)(8.5)
Multiply 2π⋅2.25.
Multiply 2.25 by 2.
4.5π+2(π)(1.5)(8.5)
Multiply 4.5 by π.
14.13716694+2(π)(1.5)(8.5)
14.13716694+2(π)(1.5)(8.5)
Multiply 2π⋅1.5.
Multiply 1.5 by 2.
14.13716694+3π⋅8.5
Multiply 3 by π.
14.13716694+9.42477796⋅8.5
14.13716694+9.42477796⋅8.5
Multiply 9.42477796 by 8.5.
14.13716694+80.11061266
14.13716694+80.11061266
Add 14.13716694 and 80.11061266.
94.2477796
Find the Surface Area cylinder (8.5)(1.5)
