2 dni temu · Once we have done this, we can double our answer to get the diameter. Taking the lateral surface area formula and substituting the values 4 3 4 𝜋 for the lateral surface area and 31 for ℎ, we get 4 3 4 𝜋 = 2 × 𝜋 × 𝑟 × 3 1 = 6 2 𝜋 𝑟. Dividing both sides by 62 and then 𝜋 gives 7 = 𝑟.
2 dni temu · Calculation Formula. The formula for calculating the effective area is given by: \[ EA = \frac{P}{I} \] where: \(EA\) is the Effective Area in square meters (\(m^2\)), \(P\) is the power in watts (\(W\)), \(I\) is the incident wave intensity in watts per square meter (\(W/m^2\)). Example Calculation
2 dni temu · Archimedes' Hat-Box Theorem. Practice Problems. Proof. To prove that the surface area of a sphere of radius r r is 4 \pi r^2 4πr2, one straightforward method we can use is calculus. We first have to realize that for a curve parameterized by x (t) x(t) and y (t y(t ), the arc length is.
