How To: Calculate the circumference of a circle

This video shows how to calculate the circumference of a given circle. The video first describes the circumference or perimeter of a circle as the distance around the outside of a circle. To find the circumference we need either the radius or the diameter of the circle. When you know the diameter of the circle, the formula to find the circumference denoted by 'C' is 'pi' times the diameter, where 'd' is the diameter and 'pi' is a constant, the approximate value being 3.14. And when you are gi...

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: Draw the Simpson's Homer Simpson

The video shows you how to draw a Homer Simpson cartoon. Start off with a big circle and a smaller circle below. Draw two slightly diagonal lines to the sides, a slightly curved line below and two lines for the lower part of the head. Then add another circle on the left side of the smaller circle. Draw a small pickle shaped nose and an eyebrow above the left circle. Draw the ear just below the eye line. The hair is drawn above the ear, like an M shape. Draw the mouth and the lower lip and ext...

How To: Derive the area of a circle

This video is about deriving the area of a circle of radius 'r' using polar co-ordinate. First, we draw a circle and its radius 'r'. Then draw another radius close to it, so that it forms a small triangle-like figure. To find the area of the complete circle, divide the circle into similar small triangles. The area of each triangle is given by half the product of its perpendicular and the base. We give the angle between the two radii as d?. We get the area of the small triangle by substituting...

How To: Find the area of a circle with pi

This video shows how to find the area of a circle using a formula. The formula for area of circle is pie multiplied by square of radius. Pie is actually an infinite number but for the sake of convenience we consider the value of pie as 3.14. So we multiply the square of radius with 3.14. Radius is the distance between the center point of the circle to any of the outside arcs. It is actually half of the diameter (diameter is the distance between two arcs of a circle). As an example here the ra...

How To: Create a 3d lego brick in Illustrator

This video demonstrates how to create a 3D Lego brick using the Illustrator. In this, first a circle is made and then, by using the "transform‚" mode, another circle is made. Then by the 3D command it is converted into a 3D image. Further you can copy these circles and make them 3D just like there are in Lego bricks. You can also use the 3D mode to do the same thing to the rectangle frame on which the circles were made. So this is how a 3 D Lego brick is made. This video is useful to people w...
