Surface area of a cylinder: 2B + Ch
Word form: 2(area of base) + (circumference of base)(height)
Find the numbers you need to plug in to the formula.
Area of base:
2² = <span>12.57 m</span>²<span>
</span>
Circumference of base: 22 = 12.57 m
Height: 12 m
Plug these numbers in to the formula.
2(12.57) + (12.57)(12) = 175.98
The SA of the cylinder is 175.98 m².
