    3 dni temu · The area of a circle calculator helps you compute the surface of a circle given a diameter or radius. Our tool works both ways — no matter if you're looking for an area-to-radius calculator or a radius to the area one, you've found the right place .

  2. The formula for calculating the surface area of a circle is: Surface Area = πr². Where r is the radius of the circle, and π is the mathematical constant pi (approximately equal to 3.14). Example: Suppose you need to calculate the surface area of a circle with a radius of 5 meters. First, input the radius of 5 meters into the calculator.

  3. To calculate the area of a circle, you can use the PI function together with the exponent operator (^). In the example shown, the formula in C5, copied down, is: =PI()*B5^2 which calculates the area of a circle with the radius given in column B.

  4. 19 maj 2024 · Use these handy Excel formulas for circle and sphere calculations! Whether they’re a distant memory from school days or a recent discovery, you can easily compute them using Pi π , or as Excel dubs it, Pi().

    Area of a Circle Calculator. Use this calculator to easily calculate the area of a circle, given its radius in any metric: mm, cm, meters, km, inches, feet, yards, miles, etc.

  6. The Excel PI function returns the value of the geometric constant π (pi). The value represents a half-rotation in the radian angle system. The constant appears in many formulas relating the circle, such as the area of a circle.

  7. If you need to use Pi in a mathematical calculation, you can use the PI function by typing =PI() into a cell, which will return the numerical value of Pi to use in formulas. In this tutorial, we showed you how to use the PI function in Excel to either get the value of PI (in radians or degrees) or to perform calculations that involve this constant.
