the value of pi.
First, we need to convert the diameter from inches to feet:
72 inches = 6 feet (since 1 foot = 12 inches)
Now, we can calculate the surface area of the cylinder:
Surface Area = 2πr² + 2πrh
Radius (r) = diameter / 2 = 6 feet / 2 = 3 feet
Height (h) = 22 feet
Surface Area = 2 * 3.14 * (3)^2 + 2 * 3.14 * 3 * 22
Surface Area = 2 * 3.14 * 9 + 2 * 3.14 * 66
Surface Area = 56.52 + 413.04
Surface Area = 469.56 square feet
Therefore, the surface area of the silo, including its ceiling and floor, is 469.56 square feet.
Lucas needs to determine the surface area of a silo that is in the shape of a cylinder, including its ceiling and floor. If the height is 22 feet and the diameter is 72 inches, what is the silo’s surface area? Use 3.14 for
