The diameter of the base of the cone measures 8 units. The height measures 6 units
daser333 [38]

For this case we can find the volume and area of the cone:

V = \frac {\pi * r ^ 2 * h} {3}

Where:

V: It's the volume

A: It's the radius of the base

h: It's the height

We have to:

r = \frac {8} {2} = 4 \ units\\h = 6 \ units

Substituting:

V = \frac {\pi * 4 ^ 2 * 6} {3}\\V = \frac {96 * \pi} {3}\\V = 32 \pi \ units ^ 3

On the other hand, the area of the cone is given by:

A = \pi * r * g +  \pi * r ^ 2

Where:

A: It's the radio

g: It is the generator of the cone.

g = \sqrt {h ^ 2 + r ^ 2} = \sqrt {6 ^ 2 + 4 ^ 2} = \sqrt {36 + 16} = \sqrt {52} = 7.2

SW:

A = \pi * 4 * 7.2 + \pi * 4 ^ 2\\A = 28.8 \pi + 16 \pi\\A = 44.8 \pi \ units ^ 2

Answer:

V = 32 \pi \ units ^ 3\\A = 44.8 \pi \ units ^ 2

What is the value of the fourth term in a geometric sequence for which a1 = 30 and r = 1/2?.
Mariana [72]
\bf n^{th}\textit{ term of a geometric sequence}\\\\
a_n=a_1\cdot r^{n-1}\qquad 
\begin{cases}
n=n^{th}\ term\\
a_1=\textit{first term's value}\\
r=\textit{common ratio}\\
----------\\
a_1=30\\
r=\frac{1}{2}\\
n=4
\end{cases}\implies a_4=30\left( \frac{1}{2} \right)^{4-1}

The number of visitors to a park is expected to follow the function v(x) = 8(x − 1), where x is the number of days since opening
mina [271]
You have the function v(x) = 8(x − 1), where x <span>is the number of days since opening.

 </span><span>On the first day, there will be a ceremony with 32 people in attendance.

 Therefore, keeping the information above on mind, the </span><span>function that shows total visitors, including the ceremony is:

 f(x)=8(x-1)+32

 So, as you can see, the answer is: 
</span>
 f(x)=8(x-1)+32
