**Problem Statement:**

Each rear tire on an experimental airplane is supposed to be filled to a pressure of 47 pounds per square inch (psi). Let \( X \) denote the actual air pressure for the right tire and \( Y \) denote the actual air pressure for the left tire. Suppose that \( X \) and \( Y \) are random variables with the joint density function shown below. Complete parts (a) through (c).

**Joint Density Function:**

\[
f(x, y) = 
\begin{cases} 
k(x^2 + y^2), & 33 \leq x < 61, \ 33 \leq y < 61 \\
0, & \text{elsewhere}
\end{cases}
\]

---

**Problem Parts:**

(a) **Find \( k \):**

\[
k = \frac{3}{10698464}
\]

(b) **Find \( P(33 \leq X \leq 44 \ \text{and} \ 51 \leq Y \leq 61) \):**

\[
P(33 \leq X \leq 44 \ \text{and} \ 51 \leq Y \leq 61) = \boxed{\quad}
\]

(Simplify your answer.) 

---

**Notes:**

To solve this problem, you would need to integrate the joint density function over the specified intervals for \( X \) and \( Y \), using the constant \( k \) found in part (a).
