To find the area of a circle, the formula is pi*r2, and the circumference is 2pi*r
Now plug in the information given.
Circumference is 50pi.
50pi = 2pi*r Divide both sides by pi.
50=2*r Divide both sides by 2.
25 = r The radius equals 25.
Now to find the area, using pi*r2. We know the radius is 25.
pi*(25)2 Find the square of 25.
pi*625
The area of the circle is 625pi square units (about 1963.5 square units)

JordanThe area of a circle is calculated using the formula A = πr^2. Given that the circumference of the circle is 50π, we can determine the radius using the formula C = 2πr, where C is the circumference. So, 50π = 2πr. Solving for r gives us the radius as 25. The area of the circle with radius 25 is then A = π(25)^2 = 625π.

If the area of a circle is 201.06 then the circumference of the circle is?
The formula to find the circumference of a circle is C = 2πr, where r is the radius of the circle. To find the circumference, you first need to find the radius by using the formula for the area of a circle (A = πr^2). Given that the area is 201.06, you can solve for the radius. Once you have the radius, you can plug it into the formula C = 2πr to find the circumference.
What is the area of a circle with circumference 9.42?
The formula for the circumference of a circle is 2πr, where r is the radius. We can rearrange this formula to solve for the radius: r = circumference / (2π) = 9.42 / (2 * 3.14159) = 1.5. Then, using the formula for the area of a circle (πr^2), the area is π * 1.5^2 ≈ 7.07 square units.
How do you find the circumference of a circle when you know the area?
To find the circumference of a circle when you know the area, you first need to find the radius of the circle using the formula for the area (area = πr^2). Once you have the radius, you can calculate the circumference using the formula for the circumference (circumference = 2πr).
What is the circumference of a circle with a 10 radius?
Area of a circle is Pi x r x r (Pi r squared.) 3.142 x 10 x 10 square feet = 314.2 square feet.
What is the Amount of space a circle takes up?
The amount of space a circle takes up is determined by its area, which can be calculated using the formula A = π * r^2, where r is the radius of the circle.
