The area of a quarter circle is the area of one-fourth part of the whole area of the circle. Hence, the area of quarter circle is 14 of the area of that circle.
Equation and Area of the Circle: In geometrical mathematics, a circle is defined as a shape of round periphery and it is a two-dimensional shape and the periphery of the circle has a constant distance from the fixed point (center) of the circle and the constant distance...
Circumference of a Circle = 2πr, where r = Radius of the circle Now, what is instead of the radius we are given the diameter of a circle, how do we calculate the circumference? Since, diameter ( d ) = 2 x radius, we substitute 2r = d in the above equation to get, ...

circle The set of all points in a plane that are the same distance from a given point called the center circumference the outer boundary of a circle; the perimeter Circumference of a circle C=2πr or C=πd Circumference (dimensions) defined by units, cm, inches, or other units of measu...
Measure the length of one side of the square. It doesn't matter which side you use, since the sides of a square are all the same length. Multiply the measurement by itself to find the area. For example, if one side of the square is 5 feet, the equation is 5 time 5 equals 25. ...
of a circle to calculate area using the circle's diameter,d. Since 2_r_ =dis an unequal equation, both sides of the equal sign must be balanced. If you divide each side by 2, the result will ber= _d/_2. Substituting this into the general formula for area of a circle, you have...
If A is the area of a circle with radius r and the circle expands as time passes, find dAdt in terms of drdt. Differential Calculus Rate of Change Mathematically, rates of change are represented by derivatives, so we will use concepts from Differenti...
