WebAbū Rayḥān Al-Bīrūnī, a pioneering Muslim scientist figured out a truly remarkable and ingenious method to calculate the radius of the earth (and subsequently its circumference). This method was very simple yet accurate, requiring just four measurements in all to be taken and then applying a trigonometric equation to arrive at the solution. WebIf the earth is a globe, and is 25,000 English statute miles in circumference, the surface of all standing water must have a certain degree of convexity—every part must be an arc of a circle. ...

Do you know what the volume of an official FIFA World Cup soccer ball called size 5 is? Or basketball, size 7? Let's check! Enter the radius of the sphere. For size 5 soccer ball radius should be equal to 4.3-4.5 in. Let's take 4.4 in. WebWe can use this to estimate the circumference if we know the diameter, and vice versa. For example, using 3.1 as an approximation for \pi, if a circle has a diameter of 4 cm, then the circumference is about (3.1)\boldcdot 4 = 12.4 or 12.4 cm. The relationship between the circumference and the diameter can be written as \displaystyle C = \pi d onlysalesleads.com
