A 45-foot diameter circle has an area of 1,590.4 square feet.
A 45-foot circumference circle has an area of: 161.1 square feet.
Using 3.14 as Pi the area of circle is: 6358.500000000001
The radius length r of the inscribed circle equals to one half of the length side of the square, 10 cm. The area A of the inscribed circle: A = pir2 = 102pi ≈ 314 cm2 The radius length r of the circumscribed circle equals to one half of the length diagonal of the square. Since the diagonals of the square are congruent and perpendicular to each other, and bisect the angles of the square, we have sin 45⁰ = length of one half of the diagonal/length of the square side sin 45⁰ = r/20 cm r = (20 cm)(sin 45⁰) The area A of the circumscribed circle: A = pir2 = [(20 cm)(sin 45⁰)]2pi ≈ 628 cm2.
141.372 Circumference equals pi times the diameter: 45 x 3.1416 = 141.372 If you memorize the formula, it will serve you well.
Using 3.14 as Pi the area of circle is: 1589.6250000000002
If radius = 45 mm, then area = 6361.7 mm2 (to 1 dp).

A 45-foot circumference circle has an area of: 161.1 square feet.
One eighth of a full circle is equal to 45 degrees. A full circle is 360 degrees, so to find one eighth of that, you divide 360 by 8, which equals 45. This is a fundamental concept in geometry and trigonometry, where understanding angles and their measurements is crucial.

Presumably you mean the area of a circle? Area of a circle = pi*radius2 Area = pi*3.82 = 45.36459792 Area = 45 square meters to the nearest square meter.
To calculate the volume of air you have to find know how big the area of air for example the area is 45 and the height is 20. all you have to do is times both numbers, 45 times 20 equals 900. So that is the volume.
You must think of the unit circle. negative theta is in either radians or degrees and represents a specific area on the unit circle. Remember the unit circle is also like a coordinate plane and cos is the x while sin is the y coordinate. Here is an example: cos(-45): The cos of negative 45 degrees is pi/4 and cos(45) is also pi/4
Divide the angle sector by 360 and multiply it by 24 square meters. The area is equal to 3 square meters.
