Answer:
The answer is

Step-by-step explanation:
First you have to find the radius of sphere by dividing diameter by 2 :

Let diameter = 14,


Next you have to use the volume of sphere formula :

Let r = 7,



1a+18=7a
18=7a-1a
18=6a
6a=18
a=18/6
a=3
The Y intercept is 0, and the Slope is 1
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


so, the difference is always the same, 2
Hence, the answer is a Arithmetic sequence
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

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