Is 0.16 pie a rational number?
(pi) itself is an irrational number. The only multiples of it that can be rational are (pi) x (a rational number/pi) .
What prime number is a common factor of 20 and 32?
The only prime number that is a factor of both 20 and 32 is 2. Note: The only prime factor of 32 is 2. 32 = 2 x 2 x 2 x 2 x 2.
What is a prime factor of the composite number 20?
2 and 5
How do you take a larger number from a smaller number?
add a tenth of the larger number to the smaller number so the smaller number is actually the larger number or you could refare to 6 over 4 in pi over 56 = x square 2 pi But no-one understands that
What is the octal equivalent of decimal number 20?
24 (2 x 81 + 4 x 80)
What is the volume of a cylinder with a height of 5 and radius of 2?
The volume of a cylinder equals the area of the base times the height, which equals pi x radius squared x height. Inserting the numbers, V = pi x (2 m.) squared x 5 m. = pi x 4 m. squared x 5 m. = 20 x pi meters cubed or 20 x pi cubic meters.
If the Circumference of a circle is 20 what is its radius?
Just divide the circumference by (2 x pi). Pi is about 3.1416.
Sin x - cos x 0 0?
sin x - cos x = 0sin x = cos x(sin x)^2 = (cos x)^2(sin x)^2 = 1 - (sin x)^22(sin x)^2 = 1(sin x)^2 = 1/2sin x = ± √(1/2)sin x = ± (1/√2)sin x = ± (1/√2)(√2/√2)sin x = ± √2/2x = ± pi/4 (± 45 degrees)Any multiple of 2pi can be added to these values and sine (also cosine) is still ± √2/2. Thus all solutions of sin x - cos x = 0 or sin x = cos x are given byx = ± pi/4 ± 2npi, where n is any integer.By choosing any two integers , such as n = 0, n = 1, n = 2 we can find some solutions of sin x - cos x = 0.n = 0, x = ± pi/4 ± (2)(n)(pi) = ± pi/4 ± (2)(0)(pi) = ± pi/4 ± 0 = ± pi/4n = 1, x = ± pi/4 ± (2)(n)(pi) = ± pi/4 ± (2)(1)(pi) = ± pi/4 ± 2pi = ± 9pi/4n = 2, x = ± pi/4 ± (2)(n)(pi) = ± pi/4 ± (2)(2)(pi) = ± pi/4 ± 4pi = ± 17pi/4
What is the formula for an area of a circumference?
(i) Circumference = pi x Diameter (ii) Area = pi x Radius^2 From (i), D = C/pi R= (C/pi)/2 Substituting into (ii), Area = pi x ((C/pi)/2)^2 Simplifying: A = (C^2) / (4 x pi)
How many square inches are in 20 inches diameter circle?
Area of any circle = (pi) x (Radius)2Radius = 1/2 of diameterArea = (pi) x (10)2 = 100 pi = 314.16 square inches (rounded)
What is radius of circle with a circumference of 31 feet?
Circumference of a circle = (pi) x DiameterDiameter = 2 x radiusCircumference = (pi) x (2 x radius)(2 x radius) = Circumference/piRadius = Circumference/(2 x pi) ==> Over to you.
The formula for the circumference of a circle is what?
Circumference of a circle = diameter*pi or 2*pi*radius
Is there a number when multiplied by pi equals a number without decimals?
Yes. 1/pi. pi x 1/pi = 1.
What's the formula for the circumference of a circle?
2 x pi x radius or pi x diameter where pi = 3.14159265
What is 2 pi radius?
Pi is the circumference of (distance around) a circle divided by its diameter (largest distance across). The radius is one-half of the diameter. 2 pi radius means two times pi times the radius or 2 x pi x radius. You can multiply in any order so this is the same as 2 x radius x pi. 2 x radius = diameter diameter x pi = circumference (distance around) 2 pi radius is the circumference of a circle
Circumference of a Sphere?
pi x Diameter or pi x 2 radius
How do you find the surface area for a cylinder?
2 x pi x radius x height + 2 x pi x radius square
