WebCircumference = 2 × π × Radius In Summary: Remembering The length of the words may help you remember: Radius is the shortest word and shortest measure Diameter is longer Circumference is the longest Definition The circle is a plane shape (two dimensional), so: Area The area of a circle is π times the radius squared, which is written: A = π r 2
WebApr 6, 2024 · The formulas linking the diameter and area of a circle reads area = π × (diam/2)2 and diam = 2 × √ (area / π). For instance, the diameter of a circle with unit area is approximately equal to 1.128 because diam = 2 × √ (1 / π) ≈ 1.128. What is the radius of a circle of area 10? The radius is approximately equal to 1.785.
Web5 years ago. You just need to use the equation. First, 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. kofferraum bmw 420 cabrioWebDiameter of the circle, D = 15 cm Thus using the formula, Substituting the value of diameter, R = 7.5 cm Q.2: Find the radius of the circle whose area is 300 square cm?
