what is 2 pi r squared How to Calculate the Area The area of a circle is Pi times the Radius squared A r2 or when you know the Diameter A 4 D2 or when you know the Circumference A C2 4 Example What is the area of a circle with radius of 3 m Radius r 3 Area r2 32 3 14159 3 3 28 27 m2 to 2 decimal places
Area of a Circle Area of a circle is the region occupied by the circle in a two dimensional plane It can be determined easily using a formula A r2 Pi r squared where r is the radius of the circle The unit of area is the square unit such as m2 cm2 etc The precise answer is 10 To get this result recall the formula area r 2 We transform it to the form r 2 area and so we see that the radius is equal to the square root of area Plugging in area 10 we obtain radius 10 10 3 14 3 185 1 785

In geometry the area enclosed by a circle of radius r is r 2 Here the Greek letter represents the constant ratio of the circumference of any circle to its diameter approximately equal to 3 14159 Here you will learn about using the formula boldsymbol pi r 2 text pi r squared to calculate the area of a circle given the radius diameter or circumference Students will first learn about boldsymbol pi r 2 text pi r squared as part of geometry in 7 th grade
Difference Between 2 Pi R and Pi R Squared 2 r calculates the circumference of a circle which is the distance around the circle s edge r calculates the area of a circle which measures the region enclosed by the circle s boundary The formula for the area of a circle is A r 2 where r is the radius of the circle The unit of area is the square unit for example m 2 cm 2 in 2 etc The area of a circle formula is useful for measuring the region occupied by a circular field or a plot
