The radius of a circle is defined as a line segment that joins the center to the boundary of a circle. The distance from the center point to any endpoint on the circle is called the radius of a circle. Learn about the radius formulas with solved examples
Since perfect squares are numbers that can be expressed as a product of an integer with itself which ultimately gives us the square of that integer. The perfect squares formula can be expressed as:P=n×n=n2 where P denotes a perfect square number and n denotes an integer....

By Vieta’s Formula,a is the sum of the integral zeros of the function, and so a is integral. Because the zeros are integral, the discriminant of the function, a2−8a, is a perfect square, say k2. Then adding 16 to both sides and completing the square yields (a−4)2=k2+...
What is the formula for surface tension? Cohesion Force: The force of attraction between the molecules of the same substance is called the cohesion force. It is also called the intermolecular attraction. Adhesive force is the force of attraction between the molecules of different substances. ...
Perimeter of a Square:The perimeter of a square is the sum of all its sides. Consequently, since all sides of the perimeter are of equal lengths, the perimeter of a rectangle is four times the length of one of its sides.Answer and Explanation: ...
Step 1: Understand the relationship between the side length and the diagonal of a square.The diagonal d of a square is related to the side length a by the formula:d=a√2 Step 2: Set up the equation using the given diagonal.Given that the diagonal d is 6, we can write:a√2=6 Ste...
Step 5: Solve the System of EquationsNow we have a system of equations: 1. a+b=92. ab=20 Let a and b be the roots of the quadratic equation x2−(a+b)x+ab=0: x2−9x+20=0 Using the quadratic formula: x=9±√92−4⋅202 ...
