Heart b what is the total surface area of the cylinder from part A radius is 2.5 m and height is 7 m use 3.14 pi
The total surface area of a cylinder can be calculated by adding the lateral surface area and the areas of the two circular bases.
The lateral surface area of a cylinder is given by the formula 2πrh, where r is the radius and h is the height.
The area of a circle is given by the formula πr^2, where r is the radius.
In this case, the radius is given as 2.5 m and the height as 7 m. So we can calculate the surface area as follows:
Lateral Surface Area = 2πrh = 2 * 3.14 * 2.5 * 7 = 109.4 m^2
Area of the Circular Base = πr^2 = 3.14 * (2.5)^2 = 19.625 m^2
Total surface area = Lateral Surface Area + 2 * Area of the Circular Base
= 109.4 + 2 * 19.625
= 109.4 + 39.25
= 148.65 m^2
Therefore, the total surface area of the cylinder is 148.65 square meters.
