Surface Area of a cylinder (= 2πr (r + h)),
The radius of the cylinder is 8 inches and its height is 12 inches.
Surface Area of a cylinder (= 2 (π) (8) (8 + 12) = 320 π)

3- E
(average = frac{sum of terms}{number of terms})
(18 = frac{13+15+20+x}{4})
(72 = 48 + x ⇒ x = 24)

4- C
Let (x) be the original price.
If the price of the sofa is decreased by (25%) to ($420), then: (75 %) of (x=420 ⇒ 0.75x=420 ⇒ x=420÷0.75=560)

5- E
Frist, factor the function:
(x (x+2)(x+3))
To find the zeros, (f(x)) should be zero.
(f(x)=x (x+2)(x+3)=0)
Therefore, the zeros are:
(x=0)
((x+2)=0 ⇒ x= -2)
((x+3)=0 ⇒ x= -3)

6- C
Use simple interest formula:
(I=prt)
(I = interest, p = principal, r = rate, t = time)
(I=(8,000)(0.045)(5)=1,800)

7- E
((3.2 × 10^6) × (2.6 × 10^{−5}) = (3.2 × 2.6) × (10^6 × 10^{−5}) = 8.32 × (10^{6 + (−5)} ) = 8.32 × 10^1)

8- E
The formula of the volume of the pyramid is:
(V=frac{l ×w ×h}{3})
(V=frac{6×6 ×12}=144 cm^3)

9- E
the triangle ABC is reflected over the (y)-axis, then all values of (y)’s of the points don’t change and the sign of all (x)’s change.
(remember that when a point is reflected over the (y)-axis, the value of (y) does not change and when a point is reflected over the (x)-axis, the value of (x) does not change).
Therefore:
((−1,6)) changes to ((1, 6))
((−2, 5)) changes to ((2, 5))
((5, 8)) changes to ((−5, 8))

10- E
Use Pythagorean theorem:
(a^2 + b^2 = c^2)
(12^2 + 16^2 = x^2)
(144 + 256 = x^2)
(400 = x^2)
(x = 20)
