To find the area of a circle given the radius,plug in the value of the radius to the formula A = pi r^2. To do this, first you square the radius, then you multiply the result by pi. If the radius of your circle is 2, write out of your formula using 2 instead of r: A = ...
Using the Radius to Find the Other Measurements The radius is used to define the diameter, circumference, and area of the circle. The diameter of the circle is a straight line through the center point. So, the length of a diameter is given by twice the radius. That is, {eq}d = 2r...

You can find the circumference of a circle by using the measurement of its diameter, radius or area. The circumference of a circle is the distance around the circle's edge from one point, meeting back at that point. Knowing how to calculate a circle's circumference can be useful in math ...
Find ?_C ( a r c t a n ( x^3 ) ? i n x ? 3 y + y^2 ) d x + ( 4 x + 2 x y + 2 y^2 ) d y where C is the positively oriented circle centered at (1, 3) with radius 4 a. How to find the center of a circle using the points (2,8) (-4,6) (1,-1)...
To find the area of a circle inside a right angled triangle, we have the formula to find the radius of the right angled triangle, r = ( P + B – H ) / 2. Given
Divide the area by pi then square root your answer which will give the radius of the circle and use 2*pi*radius to find the circumference. Wiki User ∙ 14y ago This answer is: 👍👎Add a CommentAdd your answer: Earn +20 pts Q: How do you find the circumfrence of a circle...
of the circle. A sector is best thought of as a piece of pie, and the bigger the angle of the sector, the bigger slice of pie. Each side of the segment is a radius of the circle. You canfind the radiusof both the sector and the circle by using the sector's angle and area. ...
Area: A=πr2 (π = 3.14) Perimeter (Circumference): C=2πr (π = 3.14) Diameter: d=2r Here is asimpleJava programto find out Diameter, Area and Circumference of any given circle provided you have radius. Create class CrunchifyCircleDiameterAreaCircumference.java ...
The formula for the area of a circle is "pi x r2" where "r" is the radius of the circle. So if you have a pool with a diameter of 20 feet, the radius is 10 feet, and the formula would be calculated in this way: 3.14 x 102= 314 square feet. ...
