The answer is 196/3 pi in^3. All you have to do is multiply 7x7, then you have to multiply that by 1/3 and 4, and you get 65.333333333. Then, you have to turn it into a fraction. You have to multiply 65 by 3, then add one, and you get 196/3 pi in^3.
Multiply the numerators together and the denominators to get the ending fraction.
Ex: 3/4 x 3/4 = 9/16, and simplify if needed.
