Solve the exponential equation \( 2^{3x} = 64 \).

Express 64 as a power of 2: \( 64 = 2^6 \).

Therefore, \( 2^{3x} = 2^6 \).

Since the bases are the same, equate the exponents: \( 3x = 6 \).

Solving for \( x \), \( x = \frac{6}{3} = 2 \).

The diameter of the circle is equal to the side length of the square, which is 10 cm.

Thus, the radius \( r \) is \( \frac{10}{2} = 5 \) cm.

The area \( A \) of the circle is \( \pi r^2 = \pi \times 5^2 = 25\pi \) square cm.

Approximating, \( A \approx 25 \times 3.1416 = 78.54 \) square cm.

The probability of event A occurring is \( \frac{3}{5} \) and the probability of event B occurring is \( \frac{1}{2} \). If events A and B are independent, what is the probability of both A and B occurring?
