Question 3: Explain what is the formula of semi-circle perimeter? Answer: The circle’s circumference formula, C, is C = 2 * pi * r. A semicircle means half a circle. Therefore, in order to find the area of a semi-circle, one would need to divide the perimeter formula by two. Qu...
Circles: Circles are the two-dimensional shapes defined in mathematics as the set of infinite points at same distancerfrom a definite point. Circles may be found all around us in nature. The bike tyres, coins, omelette, cakes, pizzas and many other things that we see around us may be fo...
a = pi*k./14000; Xk = cos(10*a).*(1-0.5*cos(16*a).^2); Yk = sin(10*a).*(1-0.5*cos(16*a).^2); Rk = 1/200 + 0.1*(sin(52*a)).^4; figure() % you need to specify the third argument, the size of the markers in points % the factor 5000 is experimentall...
Acircleis a closed curve formed by a set of points on a plane that are the same distance from its center. The area of a circle is the region enclosed by the circle. The area of a circle is equals to pi (π) multiplied by its radius squared. ...

The diameter of a circle is 40 m. What is the area of the circle in terms of pi? If the circumference of a circle is 26 \pi cm, then what is the radius of the circle? Find the radius of a circle whose circumference is equ...
The formula for the circumference of a circle isC=π×dC=π×d, or it can be written asC=2×π×rC=2×π×r. Either one works! Now, you may be asking, “Well where did pi come from, and why do we all the sudden get the circumference if we multiply said pi by our diameter?

In a plane, if we draw two circles then we can see that there are at most two intersection points. Now: If we draw n circles in a plane then there will be nC2 pairs of circle. Since: Each pair intersect at most two points. ...
