How do you calculate the volume of an cylindrical tank?
you calculate the Area of the circle at the end of the Cylinder and then multiply it by the lenght to the second circle at the end of the cylinder Circle area= Radius*Radius* pi pi being 3.14159265
How do you prove using a diagram that the magnitude of the sum of two vectors is less than or equal to the sum of the magnitude of the two vectors?
You could draw a circle [center at origin] with radius of (a + b), for the two magnitudes a and b. This represents the sum of the magnitudes. Then draw one of the vectors starting at the origin [suppose it's vector a], and then draw a circle centered at the endpoint of vector a, with a radius of b. Drawing a circle demonstrates how the second vector can point in any direction relative to the first vector. The distance from the origin to a point on this second circle is the magnitude of the resultant vector. Graphically this second circle will be entirely inside the first circle and touching it at just one point. Since it lies within the first circle, the distance from the origin to a point on that circle will be less than or equal to the radius of the first circle.
If the circumstance of a 1 circle is equal to the diameter of the 2 circle then what is the area of the 2 circle?
let the circumference of the first circle be X. The formula for the area of a circle is pi multiple by radius squared. pi can be y so it is yr2. The radius for the second circle is half the diameter so half X. therefore the are is y(0.5X)2. BTW: is this your homework? :)
The second hand on a watch moves through a complete circle every minute The motion of the second hand on a watch is best described as?
Angular motion.
