How To: Approximate the area under a curve using rectangles

The idea of finding the area under a curve is an important fundamental concept in calculus. Consider a function y = f(x). Now the area under the curve is to be calculated. The area under a curve problem is stated as 'Let f(x) be non negative on [a, b]. Find the area of the region lying beneath the curve y = f(x) and above the x-axes, from x = a to x = b. Note that finding the area under a curve will imply that you are dealing with a non negative function. The way to approach is to divide the ...

How To: Find the area of a circle when you know the diameter

In this video, it is shown how to calculate the area of a circle where the diameter is given. The formula for calculating the area of a circle is pi multiplied by square of radius. Radius is actually half of the diameter. In this video, the diameter is given as 10.6 meters. Hence, the radius will be half of 10.6 which is equal to 5.3 meters. Now, to find the area we shall multiply pi with the square of 5.3. Square of 5.3 is 28.09. If we multiply 28.09 with pi we shall get the area of the circ...

How To: Find the circumference of a circle quickly

In this instance we are going to Find the circumference of a circle by applying formula C=2pr where 'C' is circumference of a circle, approximate value of 'p' is 3.14 because it is irrational number and 'r' stands for radius i.e. half of diameter. So by applying this formula we can easily calculate circumference of a circle if radius is given or we can also calculate radius if circumference of a circle is given. One thing to remember is that unit we use for circumference of a circle is cm, in...
