Formula and result of area of circle?
The formula for the area of a circle is: Area = (pi) x (Radius)2 . When you know the radius of the circle and you use it to calculate the area of the circle, the result will be equal to (pi) x (Radius)2 .
What is area of a circle with radius of 2 cm?
A circle with a radius of 2 cm has an area of 12.57 square cm.
Why do you use the radius in the formula of finding the area of a circle?
Area of circle = pi*(radius)2
What is the radius of a circle if the area is 4?
The radius of the circle is 2 units. * * * * * If the area is 4 units, the radius is 1.128 units
How do you fine the area of a circle given the radius of the circle?
Area of a circle = (pi) x (radius)2 (pi) = about 3.1416 or about 22/7 . (It can never be written down exactly.) (radius)2 = (radius) x (radius)

What is the area in square cm of the circle if the radius is 12 cm?
Area of ANY circle is (pi) x (radius)2 .
What do you multiply the radius by?
circumference of a circle = 2*pi*radius area of a circle = pi*radius squared
What is the formula for a circle radius r?
Area of a circle = pi*radius2 Circumference of a circle = 2*pi*radius or diameter*pi Diameter of a circle = 2*radius
What is the diameter of a circle if the radius is 2?
A circle with a radius of 2 units has an area of 12.57 square units.
What is the area of a circle if the radius is 19mm?
The area is (pi) times (the radius)2 , just as it is in any other circle.
What is the radius of a circle with an area of 12.57cm2?
The radius is 2 cm
What is the surface area of a circle with a radius of 2?
area of a circle = pi * radius ^2. Ans = 3.14159 * 2^2 = 12.57 square units, given the radius being 2 units.
