Answer:
Step-by-step explanation:
The formula for the volume of a sphere is:
where r is the radius.
So when you plug in 6 for r and you get:
Area of triangle = 0.5*(base)*(height)
Area of triangle = 0.5*(5)*(12)
Area of triangle = (0.5*12)*5
Area of triangle = 6*5
Area of triangle = 30 square inches
Answer:
4) Volume model = 1723 ft³
5) The percentage of the original tank is 51200% of the mock-up
Step-by-step explanation:
4) ∵ The volume of the main tank is 882,158 ft³
∵ The dimension of the scale model is 1/8 of the original model
∵ V model/v original = (dimension model/dimension original)³
∴ Volume model/882,158 = (1/8)³
∴ Volume model = (1/512) × 882,158 = 1722.965 = 1723 ft³
5) The percentage of the original tank is
(882158/1722.965) × 100% = 51200%
