WebFind the area with this circle area formula: Multiply Pi (3.1416) with the square of the radius (r). Area = 3.1416 x r squared. The radius can be any measurement of length. This calculates the area as square units of the length used in the radius. Example: The area of a circle with a radius (r) of 3 inches is: Circle Area = 3.1416 x 3 squared. WebBecause there is a 3 in front of x^2, you will divide both sides by 3 to get x^2-2x=5. Next, you want to add a value to the variable side so that when you factor that side, you will have a …

WebFeb 2, 2024 · The circle perimeter formula is: p = 2πr, where p is the circle's perimeter, r is the radius, and π is a constant equal to approximately 3.14159265... You can also express the perimeter in terms of the diameter ( d ), remembering that r=d/2: p = πd. 💡 The number π is a constant equal to the ratio of the circumference to the diameter (or ... WebFirst, find the equation for the circle. Like this, x^2 + (y - 3)^2 = 9. Then, input the x and y values into the equation. If it's bigger than 9, the point is outside of the circle, if it's equal to 9, the point is on the circle, and if it's smaller than 9, the point is inside of the circle.
