The radius of a cone can also be calculated using the base area. The formula looks something like this: r=ABπr=πAB where: ABAB - Base area. Using surface area You might have the total surface area of the cone, so you have the formula in the form of a quadratic equation: πr2+...
Electron beamsPlasmasResonant frequencyBroadband antennasBroadband communicationTo study electromagnetic radiation induced by electron beam injection from the space shuttle, the electromagnetic dispersion equation of a finite-radius cold electron beam in a neutralizing background was solved numerically. The ...
The volume V of a cone is given by the formula: V=13πr2h Substituting h=r into the volume formula gives: V=13πr2r=13πr3 3. Set the volume equal to the given value: We know the volume is 72πcm3, so we set up the equation: 13πr3=72π 4. Cancel π from both sides: ...
