How do you work out the radius?
C=2*pi*r Radius is the circumference of the circle divided by 2pi. Therefore, if the circumference was C then the following formula works out the radius: r=C/(2*pi)
How do you find the radius of a cylinder if the height is 32 feet and the circumference of the base is 135 feet?
C = 2(pi)(r) so that r = C/(2pi) = 135/(2pi) ≈ 21.5 ft.
What does circumference equals pi times d mean?
It is the formula for the circumference C of a circle where D is the diameter. C = (pi) D
Can you develop a formula for the area of a circle as a function of its circumference?
It's pretty straightforward. The circumference of a circle is given by the equation C = 2[Pi]r, which can be rewritten as r = C/2Pi. The area of a circle is given by the equation A = [Pi]r2. Substituting for r in that equation gives us A = Pi(C/2Pi)2 = [Pi]C2/4[Pi]2 = C2/4Pi So, A = C2/4Pi. You can see that the area of a circle is proportional to the square of its circumference, so if you double the circumference, you quadruple the area. If you triple the circumference, the area increases ninefold! If you like, you can remember the formula as A = kC2, where k = 1/4Pi = 0.0796
How did 169 equals C squared?
Because the value of C equals 13
What is the formula form the radius of a circle?
well, technically since the formula for circumference is c=2pir, technically r=c/2pi (otherwise stated as radius equals circumference divided by two pi).
How do you determine the circumference of a circle if the radius is given?
Use this formula where r is the radius: C = 2Pi(r)
What is the radius fomula?
r = c/2pi (radius of a circle equals the circumference divided by (2 x pi)
Resonant frequency formula for parallel circuit?
What is frequency of parallel resonance formula?
Which of these formulas is rewritten form the original formula to solve for b a equals 2b plus c?
b= 1/2 (a - c)
What is the formula called a equals b b equals c therefore a equals c?
The Transitive Property of Equality.
How do you find the diameter if you already have the circumference?
The formula for circumference is C=2pi(r) so Basically if the circumference was 20 you would set up the equation like so 20=2pi(r) then you simply divide 2pi to both sides and your radius would be 3.18. Hope this helps!
If you are given the equation of an normal sine curve how would you determine its period?
a normal sine curve exists with the formula Asin(Bx+C)+D. The formula to derive a phase shift would be such: 2pi/B (for whatever value B exists at). Thus, for a normal sine curve (sin(x) we would get 2pi/1, and arrive at 2pi for the period.
What is the formula called a equals b b equals c therefore a?
That is not a formula, it is the transitive property of equality.
How do you work out the radius?
C=2*pi*r Radius is the circumference of the circle divided by 2pi. Therefore, if the circumference was C then the following formula works out the radius: r=C/(2*pi)
What is the formula of Radius?
Here are three: If you have the area - radius = sqrt( A/Pi ) If you have the diameter - radius = D/2 If you have the circumference - radius = (C/(2Pi))
How do you find the radius if circumference is given?
Divide the circumference by 2PI to find the radius. ( C = 2PI*Radius)
