So firstly, you're gonna replace the T variable with 2.2, which is the time given to us. And so the equation is gonna look like this:
and we will be solving for L.
The next thing you wanna do multiply 2 and 3.14 together, so your equation should look like this:
After that, you're gonna want to square all the terms in this equation (2.2, 6.28, and
) to remove the square root. Your equation will look like this
Next up is you're gonna multiply 32, the reciprocal of 1/32, on each side so that the equation looks like this
After, you're gonna divide 39.4384 on each side, and your equation should end up at
. And assuming from your options, they are gonna want you to round to the nearest whole number, so the best option is 4 feet.
