Problem Analysis

We are given a cylinder with a point B1 on its upper base and two line segments B1A and B1C. Points A and C lie on the lower base of the cylinder. B1A is the diagonal of the axial section B1BAA1, and its length is b. The angle between the line segments B1A and B1C is γ, and the angle between their projections on the lower base of the cylinder is β. We need to determine the total surface area of the cylinder.

Solution

To find the total surface area of the cylinder, we need to calculate the areas of the two bases and the lateral surface area.

# Base Area

The area of each base of the cylinder is given by the formula A = πr^2, where r is the radius of the base. Since the bases are circles, the radius of the upper base is the same as the radius of the lower base.

# Lateral Surface Area

The lateral surface area of the cylinder is given by the formula A = 2πrh, where r is the radius of the base and h is the height of the cylinder. In this case, the height of the cylinder is the distance between the upper and lower bases.

# Calculation of the Radius

To calculate the radius of the cylinder, we need to find the length of the line segment B1A. According to the problem statement, the length of B1A is b.

# Calculation of the Height

To calculate the height of the cylinder, we need to find the distance between the upper and lower bases. This can be done by finding the length of the line segment B1C.

# Calculation of the Lateral Surface Area

Using the radius and height calculated above, we can calculate the lateral surface area of the cylinder using the formula A = 2πrh.

# Calculation of the Total Surface Area

The total surface area of the cylinder is the sum of the areas of the two bases and the lateral surface area.

Answer

The total surface area of the cylinder can be calculated using the following steps:

1. Calculate the radius of the cylinder using the length of the line segment B1A, which is b. 2. Calculate the height of the cylinder using the length of the line segment B1C. 3. Calculate the lateral surface area of the cylinder using the formula A = 2πrh, where r is the radius and h is the height. 4. Calculate the area of each base of the cylinder using the formula A = πr^2. 5. Calculate the total surface area of the cylinder by summing the areas of the two bases and the lateral surface area.
