The side view of a cylinder is a square, the height of the cylinder is 1256 cm, then the diameter of the bottom of the cylinder is {} cm?
The height of the cylinder is the side length of the square in the side view, so the perimeter of the bottom is 1256 cm
The diameter is 1256 / 3.14 = 400
When cylindrical___ And___ When equal, its side view is a square
According to the analysis: when the circumference and height of the bottom of the cylinder are equal, its side expansion is a square
The side view of a cylinder is a square. Its height is [] times of the bottom radius
Perimeter = 2 * Pai * r
So the height is 2 * Pai times of the bottom radius
The side view of a cylinder is a square, if the height is increased by 2cm
The side view of a cylinder is a square. If the height is increased by 2cm and the surface area is increased by 12.56cm2, what is the original side area of the cylinder? Fill in the blanks: a cuboid is 28dm long, 55dm wide and 12dm high. First, it is dissolved into a cone of 90m2. What is the height of the cone? Fill in the blanks: the diameter of the cross section of a 2m long cylinder is 10cm, Cut vertically along the diameter of the cross section and divide it into two equal pieces. What is the surface area of each piece?
The side view of a cylinder is a square. If the height is increased by 2 cm, the surface area is increased by 12.56 square cm. The original side area of the cylinder is (39.44) square cm
