What is the energy stored in the bond of molecules?
There are two forms of energy stored in atoms and molecules, scalar or Potential energy -vh/2pir = -vp and vector energy cP=cmV Momentum energy. The Total stored energy is W = -vh/2pir + cmV = -vh/2pir + cP = [-vh/2pir, cP].
How do you find the diameter of a cable?
Diameter=2piR

How do you get the circumfrence if you have the radius?
C = PI Times Diameter = 2PIr
What is the perimeter of quarter circle?
The arc is one quarter of a circle so is 2pir, the other components of the quarter circle are the two radii, so perimeter is 2r+2pir = 2r(1+pi)
What you meaning of circumference?
The distance around the whole circle. The equation is piD or 2pir
If diameter is 16 what is the circumference?
C=2Pir, since r is 8. the answer would be 16pi.
How do you find the circumference by the radius?
circumference equal 2*pi*r(radius) C=2PiR
How do you calculate the permieter of a circle?
2pir pi = 3.1416 r = radius = 1/2 diameter
If the circumference of a circle is 128 what is the raduis?
Circumference=2Pir so 64 is Pixr and the radius is 64/Pi
The circumference of a circle is 40 pi cm what is the radius of the circle in mm?
C = 2pir (substitute 40pi cm for C) 40pi cm = 2pir (divide by 2pi to both sides) 20 cm = r = 200 mm (since 1 cm = 10 mm)
What is a circumference of a circle whose diameter is 250 cm?
The radius is half the diameter, which is 125cm. 2pir is 2x125x3.14159 which is 785.4cm
