What is the what is the answer
ElenaW [278]
The answer would be D. 18/6. We can figure this out because in the question, it says that each shape is worth one whole. There are three shapes so that means when added, the sum is 3 and 18/6, when reduced is 3.
I hope this helped! :-)

a cone with radius of 3 feet and a height of 5 feet is placed on top of a cylinder as shown find the volume of the total figure
Darina [25.2K]

Answer: Volume of the cone = 47.12 cubic feet.

Step-by-step explanation:

You didn't finish the question so Idid the best with what I had, you also didn't include the image that I think was supposed to be included.

To solve for the full volume including the cylinder, use the cylinder's volume formula.

Volume of a cylinder = height (pi) (r^2) and then add it to the 47.12.

Volume of a cone is pi(r^2)(h/3)

plug and chug!

h stands for height and r stands for radius.

The right circular cone below has a slant height of 16.2 centimeters and a base circumference of 44 centimeters.
Goryan [66]

Step-by-step explanation:

slant height² = height² + base²

16.2²= h²+44²

16.2²-44²=h²

1936-262.44= h²

=√1673.56=√h²

h=40.91
