The volume of cylinder A is π(1^2)(3) = 3π cubic meters. The volume of cylinder B is π(3^2)(3) = 27π cubic meters. Therefore, the ratio of the volume of cylinder A to cylinder B is:
3π : 27π
Which simplifies to:
1:9
So the answer is C. 1:9.

What is the volume of the oblique cone shown round the answer to the nearest tenth the diagram is not drawing the scale
30 in radius 21 in
30 in radius 21 in
Without a diagram, it's unclear exactly what shape is being referred to. However, assuming the base of the oblique cone is a circle with a radius of 30 inches, and the height of the cone (measured along a line from the apex perpendicular to the base) is 21 inches, we can calculate the volume of the cone using the formula:
V = (1/3)πr^2h
Substituting the given values, we get:
V = (1/3)π(30^2)(21)
V = (1/3)(900π)(21)
V = 63000π/3
V ≈ 20944.22 cubic inches
Rounding to the nearest tenth gives:
V ≈ 20944.2 cubic inches
So the volume of the oblique cone is approximately 20944.2 cubic inches.
V = (1/3)πr^2h
Substituting the given values, we get:
V = (1/3)π(30^2)(21)
V = (1/3)(900π)(21)
V = 63000π/3
V ≈ 20944.22 cubic inches
Rounding to the nearest tenth gives:
V ≈ 20944.2 cubic inches
So the volume of the oblique cone is approximately 20944.2 cubic inches.
