(E) \(\)25\(\)

4. \(\)A, B\(\), and \(\)C\(\) are three unequal faces of a rectangular tank. The tank contains a certain amount of water. When the tank is based on the face \(\)A\(\), the height of the water is half the height of the tank. The dimensions of the side \(\)B\(\) are \(\)3 ft * 4 ft\(\) and the dimensions of side \(\)C\(\) are \(\)4 ft * 5 ft\(\). What is the measure of the height of the water in the tank in feet?

(A) \(\)2\(\)

(B) \(\)2.5\(\)

(C) \(\)3\(\)

(D) \(\)4\(\)

(E) \(\)5\(\)

6. If a half-full \(\)4\(\)-inch by \(\)2\(\)-inch by \(\)8\(\)-inch box of soymilk is poured into a right circular cylindrical glass with radius \(\)2\(\) inches, how many inches high will the soymilk reach? (Assume that the capacity of the glass is greater than the volume of the soymilk.)

(A) \(\)8\(\)

(B) \(\)16\(\)

(C) \(\)\frac{ 4 }{ \pi }\(\)

(D) \(\)\frac{ 8 }{ \pi }\(\)

(E) \(\)\frac{ 16 }{ \pi }\(\)

7. If a right circular cylinder’s radius is halved and its height doubled, by what percent will the volume increase or decrease?

(A) \(\)50\(\)% decrease

(B) no change

(C) \(\)25\(\)% increase

(D) \(\)50\(\)% increase

(E) \(\)100\(\)% increase
