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...

This video provides a demonstration for viewers to easily understand and follow along. Thi...
When a triangle is inserted in a circle in such a way that one of the side of the triangle is diameter of the circle then the triangle is right triangle. To prove this first draw the figure of a circle. Now draw a diameter to it. It can be any line passing through the center of the circle and touching the sides of it. Now making this as the side of a triangle draw two lines from the ends of the diameter to a point on the circle. Now join the center of the circle to the other vertex of the cir...
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...
Here Mr Misonet tries to teach to compute circumference of a circle when radius is given. First he convince you the formula. The circumference of a circle is proportionately equals to "pie" times of its diameter,where the value of "pie" is equal to 3.14 and diameter is equal to two times radius. Then he puts the value of the diameter of the given circle and calculate the value of the circumference and also make you understand how to multiply the numbers with decimals. And lastly he makes your...
In this video the instructor shows you the diameter, radius and also how to find the circumference of a circle using a cookie as an example. When you draw a line against the cookie passing through its center and touching its boundaries, it is a diameter of the circle. Radius of a circle is half the diameter of the circle. The length of the circle along the border of the circle is called circumference of the circle. The formula to compute the circumference of a circle is 2 * Pi * r, where r is...
Simonc1973 teaches you how to work out the circumference of a circle. You start with a circle and draw a line across the circle. That's called the diameter. You multiply the diameter with Pi, which is 3.141. The video is even more amazing being taught by Harry Chapple, a 4 year old MENSA member, who is a maths child genius. He simply takes the ruler, measures the diameter and then calculates the result of multiplying it by Pi's value. The common value for Pi is 3.14. For very accurate results...
PapaPodcast's Peter shows us how to calculate the Area and Circumference of a Circle. Area is the amount of square units used to cover a circle. Circumference is the units around the edge of a circle. To calculate these two units we must find a radius and diameter. Diameter is a segment that joins two points on a circle and passes through the center of the circle. Radius is half of this amount. Watch the rest of the video to figure out how to use the radius and diameter to get the Area and Ci...
