How to find the area of any a circle given its radius The area of a circle with radius of 14 is equal to 615.8 See the solution steps here. Calculate the area, circumference, radius and diameter of circles Find a, c, r and d of a circle Given any 1 known variable of a circle, calculate the other 3 unknowns
Circle formulas and geometric shape of a circle. To find the area of a circle with a given radius, we use the formula = πr2 where π (pi) is a constant approximately equal to 3.1416 and r is the radius of the circle In this case, the radius r is given as 14 inches Now we can substitute this value into the formula Plugging in the radius into the formula
(14)2 = 196 now multiplying by π How to calculate the area of circle from radius to calculate the area of a circle from the radius you can do so by taking the radius and multiplying it by itself With that number you then need to multiply that by pi (3.14159). The area of a circle is equal to pi times the radius squared Substitute in the value of the radius into the formula for the area of a circle Pi is approximately equal to
Raise to the power of Move to the left of The result can be shown in multiple forms. Calculate the radius, diameter, circumference, or area of a circle, and learn the formulas to find each property of a circle. Hence, area of a circle = 616. Find the area of a circle task 1
For example, if the radius is 5 inches, then using the first area formula calculate π x 5 2 = 3.14159 x 25 = 78.54 sq in Find the area of a circle given its diameter is 12 cm Apply the second equation to get π x (12 / 2) 2 = 3.14159 x 36 = 113.1 cm 2 (square centimeters) The circle is a two dimensional figure and we have to determine the area, where the area is the region or space occupied by the circular field To determine the area of a circle we have the standard formula a = π r 2 where r represents the radius.
