In this question, the volume of the cone is needed. The equation used to determine the volume of the cone is (1/3)π(r²)h
To solve for the volume,
V = (1/3)π(3²)(10)
= (1/3)(9)(10)π
= (3)(10)π
= 30π cm³
The correct answer is the first option which is 30π cm³.

Answer: A. 30π cm3

Step-by-step explanation:

The equation for cones

V = (1/3) π * r² * h

Plug in the numbers r = radius which is half of the diameter and h = height. Also leave out π because of the answer choices.

so... (1/3) * 3² * 10 = 30

30π

Murrr4er [49]

Answer:

Mean is 83.7%

And, the standard deviation is 0.033

Step-by-step explanation:

The computation of the mean and the standard deviation is as follows:

Let us assume the P be the sample proportion

Mean is 83.7%

And, the standard deviation is

$= \sqrt{\frac{p(1-p)}{n} } \\\\=\sqrt{\frac{0.837(1-0.837)}{125} }$

= 0.033

A water tank has a radius 5 feet and height 11 feet. How much water can it hold?

Semmy [17]

The water tank hold 863.50 $ft^{3}$ of water.

<h3>What is Volume of cylinder?</h3>

The volume of a cylinder is the number of unit cubes (cubes of unit length) that can be fit into it. It is the space occupied by the cylinder as the volume of any three-dimensional shape is the space occupied by it.

The water tank is in the shape of cylinder whose radius = 5 feet

and, height= 11 feet

Volume of water tank = $\pi r^{2} h$
