1. Find the surface area of the whole cylinder 2. Find the area of one of the two circles on either end of the cylinder 3. Multiply the circle's area by two and subtract their area from the total surface area 4. Now you have the surface area of an unclosed cylinder!
The area of the base of a cylinder is: pi times radius squared
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).
Find the cross-sectional area of the cylinder (pi x the radius2), the multiply that by the height of the cylinder
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
