Question 2
Part B
What is the total surface area of the cylinder from Part A? (Radius is 2.5 meters and height is 7 meters).
Use 3.14 for pi.
Part A
The lateral surface area of a cylinder can be found using the formula:
Lateral Surface Area = 2πrh
Plugging in the given values, we get:
Lateral Surface Area = 2 * 3.14 * 2.5 * 7
= 109.9 m^2
Therefore, the lateral surface area of the cylinder is approximately 109.9 m^2.
Part B
The total surface area of a cylinder can be found using the formula:
Total Surface Area = 2πr(r + h)
Plugging in the given values, we get:
Total Surface Area = 2 * 3.14 * 2.5(2.5 + 7)
= 2 * 3.14 * 2.5 * 9.5
= 150.5 m^2
Therefore, the total surface area of the cylinder is approximately 150.5 m^2.
