Answer:
9.106
Step-by-step explanation:
The circumference of a circle with a given diameter is:
We are given the diameter of 2.9 units.
Using 3.14 for pi:
The circumference is about 9.106 units.
For this problem you must do Pythagorean theorem:
In this example 10ft is c and 7ft is a (or it could be b, and you'll be solving for a instead of b. It's the same thing, since a and b are both legs)
Plug what you know into the equation:
49 +b^{2} = 100
Bring 49 to the right side by subtracting it:
b^{2} = 51
Now you still must isolate b. The opposite of squaring is taking the square root so take the square root of both sides to cancel it from the left side:
b = 7.1414
b ≈ 7 ft
