Answer:
Exact circumference is 
Approximate circumference is 
Step-by-step explanation:
We are given;
- The diameter of a circle as

We are required to determine the exact and approximate circumference of the circle.
- We know that the circumference of the circle is given by;
- Circumference = πD, where D is the diameter
Taking π as 3.14


The exact circumference of the circle is 

Thus, the approximate circumference of the circle is 
The formula for P and B is 4P + 10B = 7
Given,
The number of batteries in a packet = 4 batteries
The number of batteries in a box = 10 batteries
Sarah bought P packets and B boxes of batteries
The total number of batteries Sarah bought = 7 batteries
We have to write an expression;
Here,
4 batteries in a packet.
Sarah bought P packets of battery.
So, she bought 4P batteries
Then,
10 batteries in a box
Sarah bought B boxes of battery
So, she bought 10B batteries
That is,
Sarah bought a total of 4P + 10B batteries which is 7 batteries
Therefore,
The formula for P and B is 4P + 10B = 7
