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)

How many square feet in a 33 inch circle?
If that's the radius, use the standard formula for the area of a circle. If it's the diameter, divide it by 2 first, to get the radius.
What is the circumference of a 33 foot circle?
207.345 feet - if 33 is the radius 103.673 feet - if 16.5 is the radius
What is the radius of a circle with the diameter of 33 cm?
radiusen av 33 cm
What is the area of a 33 foot circle?
The area of a 33-foot diameter circle is 855.3 square feet.
What is diameter of a circle with radius r equals 33 in?
the diameter is 2times the radiusr=33ind=66in
What is the Difference between the perimeteres of two concentric circles is 66 Find the difference between radius?
The formula for the circumference, (C) of a circle is C = 2πr.....where r is the radius. Let R be the radius of the larger circle and r the radius of the smaller circle. Then 66 = 2πR - 2πr = 2π(R - r) Then R - r = 66/2π = 33/π ≅ 10.504 The difference between the two radii is 10.504 (3dp)
What is the area of a circle with 33 feet diameter?
Area = 855.3 feet2
What is the area of a circle with a circumference of thirty three units?
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.
What is the area of a circle with a diameter of 33?
A = 5.093 units2
What is the area of a circle with a circumference of 33?
A = 86.66 units2
What is the area of a circle with a circumfrence of 33?
Approximately 86.7 units squared.
What is the surface area of a cylinder with base radius 33 and height 55?
Total surface area = 2*pi*r*(r + h) where r is the base radius and h the height.
