Answer:
i is always positive
Step-by-step explanation:
if be multiply 3 by 3 and get 9, then you multiply -2i by 2i and get -4i squared
9-4i^2 is now easy to solve unless we do now know the value of i, but since i is squared, i is always positive
Give me a second to get the answer and I’ll text you back
Answer:
the answer is 1/6
Step-by-step explanation:
I used a fraction calculator.
The formula for finding the circumference of a circle is 2πr or <span>πd
So, there are 2 ways to find it.
1) Using the diameter, you would do </span><span>π x 14.
This will give you </span><span>43.9822971503
(round the number to however many dp it says to do :) )
2) Using the radius (half of the diameter), you could do 2</span>π x 7
which will also get you <span>43.9822971503</span>
