Here, the radius is the distance from the circle’s center to its edge, and pi is a mathematical constant approximately equal to 3.14159. Triangle: For a triangle, the area formula is one-half the base times the height (A = ½ x b x h). This formula is used when you know the ...
So, the area of the shape we just drew will be the area of the rectangle, l b plus half the area of the circle, ½ x πr², where l and b are the length and breadth of the rectangle and r is the radius of the semicircle. If we draw a semicircle below a triangle, we ...
What is the center of the circle if the circle's equation is (x - 2)^2 + (y + 3)^2 = 25? What is a center of rotation in geometry? If 2 x^2 + 8 x + 24 + 2 y^2 + 12 y - 32 = 100, then what is the center point and radius of the circle? What is the distance...
What is the locus of the midpoints of all chords of length 4 in a given circle with radius of length 3? What does a circle with a line going through it mean in math? In the xy-plane, what is the radius of the circle described by x^2+2x+y^2 = 0?
The constant pi is used in a number of mathematical calculations. The formula for pi is: {eq}\pi = \frac{C}{D} {/eq} where {eq}C {/eq} is the circumference and {eq}D {/eq} is the diameter of any circle. {eq}D=2r {/eq}, where {eq}r {/eq} is the radius. The above...
in any space with fewer dimensions than that of aplane. We need two coordinates to describe any point in a circle, either x and y coordinates as in a rectilinear Cartesian space (the equation for the figure beingx2+y2=r2) or an r coordinate for the radius and aθcoordinate for the ...
This fixed point is known as the center of the circle. If a circle is divided into two halves, each half is called a ‘semicircle’. Parts of Circles Radius of circle: The distance between the center to any point on the boundary of a circle is called its radius. Diameter: Diameter is...

Let's clarify a few things. A circle's radius is the distance of a straight line from the center point of the circle to a place on the circle's perimeter. Pi is a special number in mathematics that's typically rounded up to 3.14. (In actuality it's an irrational number with an inf...
