The surface area of a (circular) cylinder is the circumference of the circle times the height If you need to add the surface of the ends then add twice the area of the end circles. Given r as the radius of the (circular) cylinder and h as the height, the
What is the formula for surface tension? Cohesion Force: The force of attraction between the molecules of the same substance is called the cohesion force. It is also called the intermolecular attraction. Adhesive force is the force of attraction between the molecules of different substances. ...
A cube has a volume of 576 cubic centimeters. What is the surface area of this cube? What is the length of a side of a cube with a volume of 343 cm^3? If the volume of a square cylinder is 128 pi cm^3 what are its dimensions?
Now that you have understood the surface area of a sphere, it’s time to derive the formula. The Greek mathematician Archimedes discovered that the surface area of a sphere is the same as the lateral surface area of a cylinder such that the radius of the sphere is the same as the ...
