A circle has radius r what is the formula for the area of the circle?
For a circle or radius r, the area is given by: area = {pi}r2 (ie pi times the radius squared)
Formula for area of circle?
A=pi(r)2 r=radius
Which quantity is multiplied by pi () in the formula for the area of a circle?
In the formula for the area of a circle, ( A = \pi r^2 ), the quantity multiplied by pi is the square of the radius ( r ). This means that the area is proportional to the square of the radius, reflecting how the area increases with changes in the radius of the circle.

What is the formula for finding an area of a circle?
The area of a circle with a known radius can calculated using the following formula where r is the radius : A = Pi(r)2
What is Pi R Squared?
The formula for the area of a circle is πr^2, where π (pi) is a mathematical constant approximately equal to 3.14159, and r is the radius of the circle. So, "pi r squared" refers to the area of a circle, calculated by multiplying π by the square of the radius. This formula is fundamental in geometry and mathematics for finding the area enclosed by a circle.

If the area is 628 what is the radius of a circle?
To find the radius of a circle with a given area of 628, you can use the formula for the area of a circle, A = πr^2, where A is the area and r is the radius. Rearranging the formula to solve for the radius, you get r = √(A/π). Substituting the given area of 628 into the formula, you get r = √(628/π) ≈ √(199.87) ≈ 14.14. Therefore, the radius of the circle is approximately 14.14 units.
What is the area of a circle with a radius of 19 centimeters?
