Answer:

Question 23: D. 287pi cm^3

Question 24: D. 50 mm

Question 28: A. 33.5 cu in

Explanation:

Question 23:
Height of cylinder = 9.5 cm

Diameter = 9.5 + 1.5

Diameter = 11

Radius = d/2

Radius = 5.5

volume of a cylinder formula: pi(r^2)h

pi(5.5^2)(9.5) = 287.375pi

287.375pi --> 287pi

Question 24:

actual height = 555.5 feet

model height = 505 millimeters

555.5/505 = 1.1

1.1 ratio

55/1.1 = 50

closest to the width of the base of the model is 50 mm

Question 28:

radius = 2 inches

Volume of a sphere = 4/3(pi)(r^3)

volume = 4/3(pi)(8)

volume = 32/3pi

volume = 33.51 cu in
