Answer part A, B, and C. (28 points)
mart [117]

A)

Two sides are 8 x 2 = 16 x 2 = 32 sq. in.

Two sides are 11 x 2 = 22 x 2 = 44 sq. in.

Top is 8 x 11 = 88 sq. in.

Total surface area: 32 + 44 + 88 =  164 square inches.

B) Area of a circle = PI x r^2

Area = 63.585

63.585 = PI x r^2

Using 3.14 for PI:

63.585 = 3.14 x r^2

Divide both sides by 3.14:

r^2 = 63.585 / 3.14

r^2 = 20.25

r = √20.25

radius = 4.5 inches.

C)

Diameter = radius x 2

Diameter = 4.5 x 2 = 9 inches.

The demand function for a product is p=30−3q where p is the price in dollars when q units are demanded. Find the level of produc
Marina86 [1]

Answer: a) Q= 5units

b) R= $75

Step-by-step explanation:

The maximum revenue is at dR/dq = 0

Revenue = price x quantity of demand = p × q

Substituting p = 30- 3q

R = (30-3q) × q

R= 30q- 3q2 (q2 = q raised to the power of 2)

dR/dq = 30- 6q = 0

6q = 30

q= 30/6= 5

q= 5 units

R = pq= 30q- 3q2

R= 30(5) - 3( 5×5)

R= 150- 75

R= $75

Goodluck...
