A=pi*radius2=pi*(diameter/2)2 A=pi*(45/2)2 = 1589.625 square feet if pi=3.14

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 circumference of a 12-foot-diameter circle is 37.7 feet.

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.

If the circumference of a circle is 45 cm the length of the diameter in centimeters is: about 14.32 cm
