6. The formula for the volume of a cone is V=1/3 tr^2 h. (Please note: The formula is read as, "Volume equals one-third pi radius squared times
height"). The radius, r, of the cone may be expressed as *
O 1.3V(V/rth)
O 2.1/3 (V/th)
O 3. V(V/3rth)
O 4. V(3V/rth)

answer: sherk

step-by-step explanation:

just give up and watch the best anime ever sherk

there is only one way to arrange all the eight relative to each other because they are not distinct. we have

now there are nine places to place an (and not more than one in one place).   because we have four symbols, we need to choose four of these nine places to insert an . order does not matter because the are not distinct.

thus there are 1 · c(9,4) ways, or, if we calculate it,

thus there are 126 ways to form such "words."
