The domain of $f(t) = \sqrt{64 - t^2}$ consists of all $t$ values for which the expression under the square root, $64 - t^2$, is greater than or equal to 0. Solving the inequality $64 - t^2 \geq 0$ gives $t^2 \leq 64$, which further simplifies to $-8 \leq t \leq 8$. This means the function is defined for $t$ values between -8 and 8, inclusive.
