Find the surface area. Use 3.14 for π. Round to the nearest whole number. SA = 2πr2+2πrh
We need to know the values of r and h in order to calculate the surface area.
r and h are both 20
Given that r = 20 and h = 20, we can plug these values into the formula for surface area:
SA = 2 * 3.14 * 20^2 + 2 * 3.14 * 20 * 20
SA = 2 * 3.14 * 400 + 2 * 3.14 * 400
SA = 2512
Therefore, the surface area is approximately 2512 square units.
