**Option 1**.

1. The area of the axial section of the cylinder is 64 cm2, and its formant is equal to the dimeter of the base. Find the total surface.

2. The height of the cylinder is 8.5 cm. The area of the cylinder by a plane parallel to the axis of the cylinder and 15 cm from it is 340 cm2. Find the radius and the lateral surface of the cylinder.

**Option 2.**

1. The area of the axial section of the cylinder is 108 cm2, and its formant is 3 times less than the diameter of the base. Find the total surface of the cylinder.

2. The area of the cross section of the cylinder by a plane parallel to the axis of the cylinder and 10 cm away from it is 720 cm2. The height of the cylinder is 15 cm. Find the radius and the lateral surface of the cylinder.
