Can someone pleaseee help meee please

Step-by-step explanation:

T is the amount of time a pendulum of specific length takes to make a full swing. So, if we know the time, we can find the length of the pendulum (in feet) that would make a full swing in that amount of time by solving for L. Replace T, time, with 2.2 seconds. Now, the equation looks like this: . Divide both sides by 2 pi, and because the directions tell us to use 3.14 as pi, we can divide both sides by 3.14 * 2, or 6.28. 2.2/6.28 = approximately 0.35 (we can round because its multiple choice and we don't need to know the exact answer). Now the equation looks like this: . Take the square of both sides: . Multiply both sides by 32: . 0.35^2 is 0.1225. 0.1225 * 32 = 3.92. Finally, L = approximately 3.92. Since we rounded down earlier, we can round up this time, so the length of the pendulum is 4 feet. Hope this helps!
