Radical Functions In this activity. you will write, solve, and graph a radical equation modeling a real-world situation. The cylindrical water tank on a semitrailer has a length of 20 feet. The volume of the tank is equal to the product of 1r, the square ofthe radius of the tank, and the length of the tank. Let V represent the volume of the tank, r represent the radius of the tank, and h represent the length of the tank. ? Question Graph the radical equation that can be used to calculate the radius, r, of the tank. Use the lowercase "r" and the uppercase "V" when entering the equation. After the equation has been entered, set the value of pi to be 3.14. + MARK + RELATIONSHIP + DATA 4 +r LINEAR EXPONENTIAL 3- QUADRATIC LOGARITHMIC CUSTOM 1 - -1- - 2- -3- +
