When the area of a circle is known, the formula for the radius is, Radius = ⎷(Area of the circle/π). if the area of a circle is given as 616 square units, then the radius is ⎷(616×7)/22 = ⎷28×7 = ⎷196 = 14 units. Radius of Circle Equation The radius of a ...
First, square the radius, then multiply it by pi: π7² = π49 = 153.86 square inches (993 square centimeters). Now That's Important Be careful! Units matter. When calculating area formula, be sure to use the same units for all measurements. You cannot, for example, multiply feet on...

The formula is {eq}Area = radius^2*\pi {/eq}. Radius to the second power means that the radius needs to be multiplied by itself, {eq}radius*radius {/eq}. Then multiply that product by 3.14, or pi, to get the area. The Formula for a Radius How Do You Find the Radius of a ...
Circles For Class 10 Area of a Circle Formula Area of any circle is the region enclosed by the circle itself or the space covered by the circle. The formula to find the area of the circle is; A = πr2 Where r is the radius of the circle, this formula is applicable to all the ci...
A is the area of the rectangle with length l units and breadth b units. Rewrite the formula for area making l as the subject. View Solution A wire of length a units is cut into two equal pieces and make a circle of radius r with one piece. Frame the formula by making r the subjec...
The curved surface area of a sphere is the same as the total surface area of the sphere since the sphere is a completely curved shape. Therefore, the formula for the curved surface area of a sphere is CSA of a sphere =4πr2, where “r” is the sphere’s radius....
When making such an evaluation, it is important to keep in mind the surface area of a cylinder unit. Both the radius and the height have to be given in the same unit, and the surface area will be the square of this unit measure. For instance, if the height and radius of the bases...
Hi I am trying to create a formula to give me a total between toays date and 14 days in future at the moment I am getting Errors )
