The surface area of a sphere is given by:
and the volume of a sphere is given by:
I can't tell you specifically what to do because you didn't bother to mention whether the "7 mi" is a diameter, radius, or circumference of the given sphere.
And by the way, "Pie" is a prepared food item, generally round in shape, with a more or less flaky crust depending on the qualtity, and, when used as a dessert item generally has a sweet filling often made of fruit, or when used as an entrée or side dish item, generally has some sort of savory filling. "Pi" is the generally accepted English language equivalent of the 16th letter of the lower case Greek alphabet, frequently rendered as  , representing the fixed but transcendental (because it is not a root of a non-constant polynomial equation with rational coefficients) irrational (because it is not the quotient of two integers) ratio between the circumference of a circle and the diameter of that same circle.
