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 teaches how to calculate the acceleration of a car. The information for this calculation is for a car that accelerates by 12 meters per second in a time of 3 seconds. So to calculate acceleration use the following formula: acceleration equals change of speed divided by time. So, using the information provided for this calculation, acceleration equals 12 meters per second divided by a time of 3 seconds. So this gives an acceleration of 4 meters per second squared.
