CHALLENGE ACTIVITY
1.10.1: Sphere volume.
Given sphereRadius and piVal, compute the volume of a sphere and assign sphereVolume with the result. Use (4.0 / 3.0) to perform floating-point division, instead of (4 / 3) which performs integer division.
Volume of sphere = (4.0 / 3.0) π r3 (Hint: r3 can be computed using *)
Volume of sphere = (4.0 / 3.0) π r3 (Hint: r3 can be computed using *)

ACTIVITY
A common error is to use double quotes rather than single quotes around a character literal, as in myChar = "x", yielding a compiler error.
Similarly, a common error is to forget the quotes around a character literal, as in myChar = x, usually yielding a compiler error (unless x is
also a declared variable, then perhaps yielding a logic error).
