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
