To get the amount of soil required to fill the urn, we need to get the volume of the urn. Given that the urn is cylindrical in shape, the volume will be given by:
V=πr^2h
radius=1.5 ft
height=3 ft
thus;
V=π*1.5^2*3
V=21.2058 ft^3
The answer is V=21.2058 ft^3
Answer:
(x - 2)(v + 3)
Step-by-step explanation:
xv + 3x - 2v - 6
= x(v + 3) - 2(v + 3)
Answer:
A
Step-by-step explanation:
To solve this problem, we need to know the formula of the surface area of a triangular prism. The formula is: A = 2

+ (a+b+c) * h
Now we can substitute values and solve
A = 2(0.5 * 4 * 3) + (3+4+5) * 20
A = 12 + 240
A = 252
That means that the answer to this question is 252 square feet.
