Given the volume of the cylinder, the diameter and height of the cylinder are required to be equal?
Let the radius of the cylinder be r, then the height h = 2R
Volume v = π r squared H = 2 π r cubic
So r = V / 2 π under the third radical
V / 2 π under H = 2 * cubic radical
Find a cylinder with diameter of 2.5cm, height of 2m, density of 7.8, weight
M = density * V = (2.5 / 2) & sup2; π * 200 * 7.8 = 1950 π G
If you find gravity, multiply it by 10
When a cylinder with a diameter of 4cm and a height of 5cm is cut into two equal parts along the bottom diameter, the surface area is increased by () square centimeter
A. 3.14×4×5×2B. 4×5C. 4×5×2
4 × 5 × 2 = 40 (square centimeter); a: the surface area has increased by 40 square centimeter
