Using 3.14 as Pi the area of circle is: 6358.500000000001
Area of circle = Pi x diameter2/4 = 3.142 x 49/4 = 38.49 sq ft
A 45-foot circumference circle has an area of: 161.1 square feet.

The diameter of a circle with a circumference of 45 cm is: about 14.32 cm
The circumference of a circle with a diameter of 45 inches is 141.37 inches.
Instead of "square footage", those who are comfortable with their math almostalways call it "area". After all, it could be square inches, square meters, or acres.Each of those would still be 'area', even though none of them is 'square footage'.Area of a circle = (pi) x (radius)2Radius = 1/2 of the diameterArea of your circle = (pi) x (22.5)2 = 506.25 (pi) = 1,590.43 square feet (rounded)
The formula to find Circumference is: C = Pi x D (Pi is 3.1416 and D is Diameter). Hence, 3.1416 x 45 = 141.372 cm Square centimeters (sq cm) are a measure of area. Circumference is measured in linear centimeters not square centimeters. The answer is 141.372 cm.The circumference of a circle is Î *d.The circumference of a circle with a diameter of 45 centimeters would be 45Î cm.
The diagonal of the square is the diameter of the circle (think about it!) so the sides of the square can be pythagorassed ie the square of the diagonal is twice the square of a side. As an example, consider a circle of diameter 50 units. the square of this is 2500 so every side of the square is the square root of 1250 units which equals sqrt 625 x sqrt 2 or 25 root 2 ie 35.355339 units, or 70.71% of the diameter of the circle. More basically, the diagonal is the hypotenuse of a 45/45/90 triangle so the sides are in the ratio 1/1/root2 or if you want the hypotenuse to be 1, the sides would be (root 2)/2. Either way, the sides are root2 times the radius of the circle, which is of course half the diameter. This is in full agreement with the 25 root2 calculated above for a 50 unit diameter circle.
