The diameter is double the radius of the circle. So you would do 9*2 = 18 feet.

The question only asks for the number though so you can just enter 18.

There are two formulas that can be used to find the volume of a rectangular prism. Find the volume using both formulas.

Rina8888 [55]

Answer:

Volume = $\frac{1}{8}$ cubic units.

Step-by-step explanation:

The volume of a rectangular prism is given by,

$V = (\textrm {Length}) \times (\textrm {Width}) \times (\textrm {Height})$ .......... (1) and

$V = (\textrm {Base Area})\times (\textrm {Height})$ .......... (2)

Now, the length of the given prism is $\frac{1}{2}$ units, width is $\frac{1}{2}$ units and the height is $\frac{1}{2}$ units.

So. from equation (1) the volume, V = $(\frac{1}{2}) \times (\frac{1}{2}) \times (\frac{1}{2}) = \frac{1}{8}$ cubic units.

Now, base area = B = $(\frac{1}{2}) \times (\frac{1}{2}) = \frac{1}{4}$ sq. units.

So, from equation (2) we get

$V = (\frac{1}{4}) \times (\frac{1}{2}) = \frac{1}{8}$ cubic units. (Answer)

A line with a slope of -1/3 passes through the point (9,3). What is its equation in point-slope form?

amm1812

The point-slope form:

$y-y_1=m(x-x_1)$

We have:

$(9,\ 3)\to x_1=9,\ y_1=3\\\\m=-\dfrac{1}{3}$

Substitute

$y-3=-\dfrac{1}{3}(x-9)$

Find the sum of the following infinite geometric series, if it exists. 2 + 6 + 18 + 54 +… Does not exist 23,567 25,982 29,034

Sladkaya [172]

Option A: The sum for the infinite geometric series does not exist

Explanation:

The given series is $2+6+18+54+.......$

We need to determine the sum for the infinite geometric series.

Common ratio:

The common difference for the given infinite series is given by

$r=\frac{6}{2}=3$

Thus, the common difference is $r=3$

Sum of the infinite series:

The sum of the infinite series can be determined using the formula,

$S_{\infty}=\frac{a}{1-r}$ where $0$

Since, the value of r is 3 and the value of r does not lie in the limit $0$

Hence, the sum for the given infinite geometric series does not exist.

Therefore, Option A is the correct answer.
