I NEED HELP PLEASE, THANKS!! :)

Answer:

The answer is

\frac{1372}{3} \pi \:  {cm}^{3}

Step-by-step explanation:

First you have to find the radius of sphere by dividing diameter by 2 :

radius = diameter \div 2

Let diameter = 14,

radius = 14 \div 2

radius = 7 \: cm

Next you have to use the volume of sphere formula :

v =  \frac{4}{3}  \times \pi \times  {r}^{3}

Let r = 7,

v =  \frac{4}{3}  \times \pi \times  {7}^{3}

v =  \frac{4}{3}  \times \pi \times 343

v =  \frac{1372}{3} \pi \:  {cm}^{3}

Arithmetic sequence

Explanation

An arithmetic sequence is a list of numbers with a definite pattern. If you take any number in the sequence then subtract it by the previous one, and the result is always the same or constant then it is an arithmetic sequence

Step 1

Let

\begin{gathered} a_1=5 \\ a_2=7 \\ a_3=9 \\ a_4=11 \end{gathered}\begin{gathered} a_2-a_1=7-5=2 \\ a_3-a_2=9-7=2 \\ a_4-a_3=11-9=2 \end{gathered}

so, the difference is always the same, 2

Hence, the answer is a Arithmetic sequence

Find the surface area of the figure below.
bulgar [2K]
To find the surface area we deconstruct the figure then add all the areas together.

The area of the rectangle on the bottom is 8*6 or 48.
The side rectangles are 5*6 or 30. 
The two triangles are \frac{8*3}{2} or 12.

48+30+30+12+12= 132.

Hope this helps!
