Find the surface area of a cylinder with a height of 12 meters and a diameter of 14 meters. Use 3.14 for and round to the nearest tenth. (1 point) meters
The formula for the surface area of a cylinder is 2πr(h+r), where r is the radius of the cylinder and h is the height.
First, we need to find the radius of the cylinder.
The diameter is given as 14 meters, so the radius is half of that, which is 14/2 = <<14/2=7>>7 meters.
Now we can substitute the values into the formula.
Surface area = 2π(7)(12+7)
= 2π(7)(19)
= 2(3.14)(7)(19)
= 6.28(7)(19)
= 86.36 square meters.
Rounded to the nearest tenth, the surface area of the cylinder is 86.4 square meters. Answer: \boxed{86.4}.
