The volume of the right cone is given by the formula V = (1/3)πr²h, where V represents the volume, r is the radius of the base, and h is the height. In this case, the volume of the right cone is 276π units³. Let's set up the equation: (1/3)πr²h = 276π. To find the value of x, we need to solve for r. Let's divide both sides of the equation by (1/3)πh: r² = 3*276. Now, take the square root of both sides to find the value of r: r = √(3*276)
Final answer is value of x can be found by calculating the square root of 3 times 276.
