The overall volume is the sum of the volume of a cylinder of height 5'9" and diameter 3'6", and a sphere of diameter 3'6" (two hemispheres = full sphere).
Volume of the cylinder = (area of the base) x (height) = pi * (diameter/2)^2 * 5.75ft = 3.1415 * (3.5ft/2)^2 * 5.75 ft = 55.32 ft^3
Volume of the sphere = 4/3 * pi * (3.5ft)^3 / 8 = 22.45 ft^3
Total volume = (Volume of cylinder) + (Volume of sphere) = (55.32 + 22.45) ft^3 = 77.77 ft^3
Answer:
Tom walked for 3.2 hours
Step-by-step explanation:
Don't know how Lee fits into this but if you can tell me, I can edit my answer
Distance travelled in heavy traffic = 40*1 = 40 miles
in light traffic = 60*2 = 120 miles
In total, he travelled = 40+120 = 160 miles
Answer:
bottom left. (arrow shaped)
Step-by-step explanation:
congruent shapes are the same size and shape
According to formula
Time in hours = d/2 + e/2
where d=distance in miles
e=difference in elevation in 1000 ft.
Therefore
d=9 miles
e=9000 ft/1000 ft = 9
Time in hours
= d/2 + e/2
= 9/2 + 9/2
= 9 hours.
