  1. 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.

  2. Map Radius Calculator. You can draw multiple circles, distances, areas or elevations, import/export data save and edit them later with a larger map! Draw a Radius around a map location. Draw a radius circle around a location in Google Maps to show a distance from that point in all directions.

  3. 21 maj 2024 · How to Draw a Circle in Excel with a Specific Radius - 3 Methods. Method 1 – Utilizing the Parametric Equation of a Circle. The parametric equations of a circle are: x = r cos (t) y = r sin (t) x, and y are the coordinate points, r is the radius of the circle, and t is the angle subtended by the radius at the center of the circle.

  4. In geometry, the circumference of a circle with radius (r) is defined by the following formula: =2πr. The Greek letter π ("pi") represents the ratio of the circumference of a circle to its diameter. In Excel, π is represented in a formula with the PI function, which returns the number 3.14159265358979, accurate to 15 digits.

  5. Create a Map chart in Excel to display geographic data by value or category. Map charts are compatible with Geography data types to customize your results.

  6. The standard equation for a circle centred at (h,k) with radius r. is (x-h)^2 + (y-k)^2 = r^2. So your equation starts as ( x + 1 )^2 + ( y + 7 )^2 = r^2. Next, substitute the values of the given point (2 for x and 11 for y), getting. 3^2 + 18^2 = r^2, so r^2 = 333. The final equation is (x+1)^2 + (y+7)^2 = 333.

  7. 22 lip 2024 · Formula to calculate the circumference and area of a circle. These are the formulas to calculate the circumference and area of a circle: c = 2πr. A = πr² = πd²/4. where: c stands for circumference; r for radius; and. d for the diameter of the circle.
