Apr 5, 2024 · First, we'll calculate the power P using the formula P = I 2 x R, where I is the current in amperes (amps) and R is the resistance in ohms. [16] These units give us the power in watts, so from there, we' can use the formula in the previous step to calculate the energy in joules. 2. Choose a resistor.
Jan 11, 2024 · To do this, just use the formula for finding the area of a circle, A = πr2. [6] Just plug the radius you found into the equation. Here's how to do it: A = π x 1 2. A = π x 1. A = π. Since π is normally rounded to 3.14, you can say that the area of the circular base is 3.14 in. 2. 3.

May 30, 2023 · Finding 10% of a number: Finding 10% of any number is the same as finding of that number. To do this, just move the decimal point one place to the left: 10% of 30 = 3; 10% of 41 = 4.1; 10% of 7 = 0.7; Finding 200%, 300%, and so on of a number: Working with percents that are multiples of 100 is easy. Just drop the two 0s and multiply by the ...
Steps to Calculate the Final Velocity of an Object Using Work-Energy Theorem. Step 1: Identify the mass of the object. Step 2: Identify the initial velocity. Step 3: Identify or calculate the work ...
4 days ago · In our example, the height of the cone is 5 inches. 5. Multiply the height of the cone by the area of the base. In our example, the area of the base is 28.27in 2 and the height is 5in, so bh = 28.27 * 5 = 141.35. 6. Now multiply the result by 1/3 (or simply divide by 3) to find the volume of the cone.
Aug 2, 2023 · 1. If you know the radius of the circle, double it to get the diameter. The radius is the distance from the center of the circle to its edge. [1] Example. If the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2, or 8 cm. 2. If you know the circumference of the circle, divide it by π to get the diameter.

Feb 12, 2010 · So our guess for the formula of f(n) is. f(n) = 3n + 1. Let’s check this formula with the data we know. When n = 5, for example, we know that f(n) = 16 (from our experimentation). And our formula says. f(5) = 3⋅5 + 1 = 16, so it seems to check out. You can check the other points from our table; they should agree with the values given by our ...
