A = 86.66 units2
The diameter of a circle that has a 33 cm circumference is: 10.5 cm (circumference divided by pi = diameter).
86.66 - 86.7 units squared
Circumference = 2 pi R = 33R = 33 / (2 pi)Area = pi R2 = pi (33)2 / (2 pi)2= (33)2 / (4 pi) = 86.66 square units
You dived the area by the circumference of the circle.
No,Circumference is like the perimiter and Area is the whole circle.
Circumference = pi*33 = 103.6725576 or about 103.673 inches
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.
If d = 33, then c = 104
Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).
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.
Remember that the formula for the circumference of a circle is 2πr, with r being the radius. So 2πr is 33. we can divide this number by pi to get the diameter. According to a calculator, 33 / π = 10.50423. Now the formula for the area of a circle is πr2. So we need to divide 10.50423 by 2. The result is 5.25211. This is r. π(5.25211)2 = 86.65987. So the area of a circle with a circumference of thirty three units is 86.65987 units.
The area of a circle that has a circumference of 16pi is: 201.1 units2
