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)
The circumference would be 50.265
The circumference of a circle of 7 inches is: about 21.99 inches. You can easily do this calculation for other circles by multiplying the diameter by Pi (about 3.1416).
The area of a circle with a circumference of 87 miles is: 385,472 acres.
The area. The circumference would be the distance around a circle
OK, SO to find the area of a circle, you find the radius (half of the diameter), and fit it into the equation πr2=A where r equals radius and A = area. The perimeter of a circle is π multiplied by the diameter. π is ≈ 3.1415296.
You dived the area by the circumference of the circle.
No,Circumference is like the perimiter and Area is the whole circle.
If the circumference of a circle is 6.28 then its area is about 3.138 square units
The circumference of a circle is the distance arround the edge of the circle. The area of a circle is how big the inside of the circle is.
Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).
The area of a circle that has a circumference of 16pi is: 201.1 units2
If the area of a circle is 28.26 the circumference is: 18.84 units.
The area of a circle, if its circumference is 20π, is: 314.16 square units.
The circumference of a circle when the area is 69cm2 is about 29.4 cm
The area of circle with a circumference of 20 is: 31.83 units squared.
The circumference would be 50.265
The circumference of a circle is given by Circumference = pi x diameter. The area of a circle is given by Area = pi/4 x diameter2. Thus for a circle with circumference c = 12 in. The area will equal a = 11.459 in2.
