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.

2π⋅(radius)2+2π⋅(radius)⋅(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)

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
