How many Square feet in a 45 ft circumference circle?
A 45-foot circumference circle has an area of: 161.1 square feet.
What is the area of a circle 90 feet in diameter?
Using 3.14 as Pi the area of circle is: 6358.500000000001
The side of a square is 20 cmfind the areas of the circumscribed and inscribed circles?
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.
What is the circumference of a circle if the diameter is 45?
141.372 Circumference equals pi times the diameter: 45 x 3.1416 = 141.372 If you memorize the formula, it will serve you well.

What is the area if the radius is 3.8 meters?
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.
How can you calculate the volume of air?
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.
Why does cos negative theta equals positive theta?
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
A circle has an area of 24 m What is the area of a 45 sector of this circle?
Divide the angle sector by 360 and multiply it by 24 square meters. The area is equal to 3 square meters.
How do you find the sector of a circle when it is 45 degrees and the radius 9?
93
How do you divide circle in 8 equals parts?
You divide 360 degrees by eight (there are 360 degrees in a circle) so each section would be 45 degrees.
