Find the surface area of a cylinder with a radius of 16 and a height of 23. Use 3.14 for π. Round your answer to the nearest te
To find the lateral area of a cylinder, multiply the circumference (πd) by the height (πdh). After you have this, you can find the total surface area by adding twice the area of the base (2πr2).(Lateral area = πdh), (Surface area = πdh + 2πr2).
The formula for the surface area of a cylinder is given by:2�r2 + 2�rhandBA + 2�rh.
First, you figure out what the area of the top of the cylinder is, which in case is pi times radius squared. Then, you multiply the answer by two. Next, you find the lateral surface area of the cylinder by multiplying the circumference times the height. Since the problem only gives us the radius of the cylinder, we use the formula, two times pi times radius times the height, in order to find the lateral surface area of the cylinder. Now the final step. Add the answer you got for the first step, plus the lateral surface area of the cylinder, and this should give you the surface area of the can of soup.
