Units for area are always squared. 3) The area can be found when given the diameter by first finding the radius. Diameter/2 = radius, which is the only missing part we need to find the area.
WitrynaThe equation for diameter of a circle from circumference is: d=c/\pi d = c/π. If written instead in terms of the radius, the diameter is very simple; it's just twice as long: d = 2r d = 2r. Dimensions of a circle: O - origin, R - radius, D - diameter, C - circumference ( Wikimedia) Area is the space contained within the circle's boundaries. Witryna28 lut 2024 · Yes a larger radius means a larger surface area, which means a stronger drag force. The net forces are gravity pulling the object down, and drag pushing the object up. When the net force is 0, as in the force from gravity is equal to the force of drag, the object is traveling at its terminal velocity. As radius increases, the force of …
