Sphere size is calculated using two measures: the volume (how much space the sphere takes up) and the surface area (the total area of the sphere's surface). Both sphere size and surface area can be easily calculated if you know the radius or diameter of
(1), where S is the specific surface of fly ash in terms of ball (cm/cm), Bis the Blaine's specific surface area of the fly ash (cm/g), and Ris the residue of the fly ash after 45 μm sieving (mass%).SELECTED DRAWING: Figure 1中居 直人...
Calculating a square area is as easy as multiplying the length by the width. But when you have a curved surface like a sphere or a cylinder, the problem can be puzzling. Luckily, mathematicians have figured out formulas for curved surfaces, so all you have to do is take a couple of sim...
Find the area of the surface of revolution generated by revolving about the x-axis the cardioid x=2cosϑ-cos2ϑ,y=2sinϑ-sin2ϑ. pictures show a cardioid with ϑ=pi and ϑ=0. Homework Equations After looking up, the formula to solving this type of equati...
differentiating the function. This concept is known as related rates. Related rates are used in many problems such as finding the rate at which two points are moving with respect to each other or finding the rate of change of volume ...
4 . π . d2= surface area of the sphere centered at the radiating source The E field causesinterferencein radio communications. Also, it does not directly correspond to the level of transmitter power. This is why the emission limits of broadcasting transmitters and short-range devices are spec...
so in this case I found the total surface area of a floating box just like you would a sphere when not told... even if you were to assume that it was on the ground with the given information you don't know which side of the box is on the floor? Is it on the...
Surface Area & Volume of Spheres How much would the volume of a sphere change if you doubled the radius? Would it also double? Let's calculate the volume of two spheres, one with a radius of 1 meter and the other with a radius of 2 meters, and see how the volumes compare. ...
If you know the distance to a third satellite, you get a third sphere, which intersects with this circle at two points. Earth itself can act as a fourth "satellite" or sphere; only one of the two possible points will actually be on the surface of the planet, so you can eliminate the...
Satellites do not give off information about angles, so the location of a GPS device could be anywhere on a sphere’s surface area. When a satellite sends a signal, it creates a circle with a radius measured from the GPS device to the satellite. When we add a second satellite, it ...
