2<\/sup>\/4\u03c0<\/strong>, where \u201cC\u201d is the circumference of the circle. We use this formula to calculate the area of a circle given its circumference.<\/li>\n<\/ul>\n\n\n\nExamples of calculating the area of a circle using Excel<\/h2>\n\n\n\n We will give three examples in the way of explaining how we can find the area of a circle in Excel.<\/p>\n\n\n\n
Example 1: Calculate the area of a circle given its radius<\/h3>\n\n\n\n In this example, we find the area of a circle that has a radius of 10 units.<\/p>\n\n\n\n <\/figure>\n\n\n\nWe use the following steps:<\/p>\n\n\n\n
\nSelect cell B2<\/strong> and type in the following formula:<\/li>\n<\/ol>\n\n\n\n=PI()*POWER(A2,2)<\/code><\/pre>\n\n\n\n <\/figure>\n\n\n\n\nPress the Enter key.<\/li>\n<\/ol>\n\n\n\n <\/figure>\n\n\n\n\nSelect cell B2<\/strong> and click Home >> Number >> Decrease Decimal<\/strong> several times to show fewer decimal places.<\/li>\n<\/ol>\n\n\n\n <\/figure>\n\n\n\nIn this case, we have decreased the result to two decimal places:<\/p>\n\n\n\n <\/figure>\n\n\n\nExplanation of the formula<\/strong><\/p>\n\n\n\n=PI()*POWER(A2,2)<\/code><\/pre>\n\n\n\n\nThis formula is derived from the algebraic formula of Area = \u03c0r2<\/sup><\/strong>.<\/li>\n\n\n\nThis formula uses the PI<\/strong> and POWER<\/strong> functions to compute the area of the circle.<\/li>\n\n\n\nThe PI function has no arguments and returns the mathematical constant of Pi<\/strong>, accurate to 15 digits.<\/li>\n\n\n\nThe POWER function returns the result of a number raised to power. Its syntax is POWER(number, power)<\/strong>. The numbe<\/strong>r argument is required, and it is the base number. The power<\/strong> argument is required, and it is the exponent to which the base number is raised.<\/li>\n\n\n\nIn this case, the POWER function returns the result of 10 raised to the power of 2. The result is then multiplied by the mathematical constant of Pi. The value returned is the area of the circle.<\/li>\n<\/ul>\n\n\n\nExample 2: Calculate the area of a circle given its diameter<\/h3>\n\n\n\n In this example, we find the area of a circle that has a diameter of 20 units.<\/p>\n\n\n\n <\/figure>\n\n\n\nWe use the following steps:<\/p>\n\n\n\n
\nSelect cell B2<\/strong> and type in the formula:<\/li>\n<\/ol>\n\n\n\n=(PI()*POWER(A2,2))\/4<\/code><\/pre>\n\n\n\n <\/figure>\n\n\n\n\nPress the Enter key.<\/li>\n<\/ol>\n\n\n\n <\/figure>\n\n\n\n\nIf need be decrease the result to show fewer decimal places as explained in Example 2.<\/li>\n<\/ol>\n\n\n\nExplanation of the formula<\/strong><\/p>\n\n\n\n=(PI()*POWER(A2,2))\/4<\/code><\/pre>\n\n\n\n\nThis formula is derived from the algebraic formula of Area = \u00bc \u03c0d2<\/sup><\/strong>.<\/li>\n\n\n\nThe POWER function returns the value of the diameter raised to the power of 2. This result is multiplied by Pi and then the product is divided by four. The result returned is the area of the circle.<\/li>\n<\/ul>\n\n\n\nExample 3: Calculate the area of a circle given the circumference<\/h3>\n\n\n\n In this example, we find the area of a circle that has a circumference of 62.83 units.<\/p>\n\n\n\n <\/figure>\n\n\n\nWe proceed as follows:<\/p>\n\n\n\n
\nSelect cell B2<\/strong> and type in the formula:<\/li>\n<\/ol>\n\n\n\n=POWER(A2,2)\/(PI()*4)<\/code><\/pre>\n\n\n\n <\/figure>\n\n\n\n\nPress the Enter key.<\/li>\n<\/ol>\n\n\n\n <\/figure>\n\n\n\n\nIf need be decrease the result to show fewer decimal places as explained in Example 2<\/li>\n<\/ol>\n\n\n\nExplanation of the formula<\/strong><\/p>\n\n\n\n=POWER(A2,2)\/(PI()*4)<\/code><\/pre>\n\n\n\n\nThis formula is derived from the algebraic formula of Area = C2<\/sup>\/4\u03c0<\/strong>.<\/li>\n\n\n\nAccording to the order of operations (PI()*4) is computed first because it is enclosed in brackets.<\/li>\n\n\n\n According to the order of operations POWER(A2,2) is calculated next because it has an exponent.<\/li>\n\n\n\n The result of POWER(A2,2) is finally divided by the result of (PI()*4) according to the order of operations. The value returned is the area of the circle.<\/li>\n<\/ul>\n\n\n\nConclusion<\/h2>\n\n\n\n For us to use Excel to find the area of a circle we must first understand the formulas used in algebra to calculate the area of a circle. The formulas that we use in Excel are derived from these formulas used in algebra.<\/p>\n\n\n\n
In this tutorial, we have explained the three formulas used in algebra to calculate the area of a circle.<\/p>\n\n\n\n
We have given three examples to explain how we can find the area of a circle in Excel: how to find the area of a circle given the radius, how to find the area of a circle given the diameter, and how to find the area of a circle given the circumference.<\/p>\n\n\n\n
