Find the radius of a circle whose area equals the area of a rectangle that measures 2 feet by 11 feet (use {eq}\pi = \frac{22}{7} {/eq}). The Area of a Circle: The area of a circle of radius {eq}R{/eq} is given as {eq}A...
Because all circles have the same shape, their different measurements are related by a set of simple equations. If you know the radius, diameter, area or circumference of a circle, it is fairly easy to find any of the other measurements.
public class Wb { double i = 5.0; double findArea() { return radius*radiu*3.14159; } public static void main(string []args) { TeastCircle myCircle = new TeastCircle();//请详细说下这里,最好举几个例子~ SYstem.out.print(myCircle.radius+myCircle.findArea());//这里也详细说下 } }反馈...
If a real world situation or high school worksheet provides the circumference of a circle as a starting value, we can still use this value to quickly find other measurements of these important geometric shapes. By solving for a circle's radius or diameter in terms of circumference we can find...
Here, the radius of the circle,r=3 units Since, the circle touches both the axes and completely lies in the third quadrant, its centre is at(-3,-3).Now, the equation of the circle is(x-h)²+(y-k)²=r²or,{x-(-3)}²+{y-(-3)}²=3²or,(x+3)²+(y+3)²...
The radius of a sphere or a circle is the distance from its center to its circumference. It is same for any point on the circle.
