86.66 - 86.7 units squared
If the circumference of a circle is 33 feet, its diameter is: 10.5 feet.
Approximately 86.7 units squared.
If d = 33, then c = 104
A = 5.093 units2
86.66 - 86.7 units squared
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.
A = 86.66 units2
If the circumference of a circle is 33 feet, its diameter is: 10.5 feet.
The diameter of a circle that has a 33 cm circumference is: 10.5 cm (circumference divided by pi = diameter).
Approximately 86.7 units squared.
Circumference = pi*33 = 103.6725576 or about 103.673 inches
If d = 33, then c = 104
The circumference of a 10 and a half inch circle is about 33 inches (32.99). (C = d x Pi)
207.345 feet - if 33 is the radius 103.673 feet - if 16.5 is the radius
Commit to memory Area(of Circle)(A) = pi)3.141592....) Multplied to the radius squared (r^2) Algebraically A = pi*r^2 pi = 3.14 ( for elementary/school purposes) r = 33 r^2 = 33^2 Substitute A = 3.14 * 33^2 A = 3.24 X 33 X 33 On the calculator/ A = 3.14 X 1089 A = 3421.1944.... units^2 A ~ 3421.2 units^2 NB You do not give the units, but whatever, they are , they are squared. e.g. )cm^2)
The area of a 33-foot diameter circle is 855.3 square feet.
