Step-by-step explanation:
SA= 2*r*r*pi + 2*pi*r*h
= 2*6*6*3.14 + 2*3.14*6*8
Answer:
With the Babylonian method
and
.
Step-by-step explanation:
- To find the square root of 600, do the following:
1. Make an initial guess: Because
and
you can start with
as your initial guess.
2. Apply the formula:
where 

The number
is a better approximation to 
3. Iterate until convergence:
For this apply the formula:
Convergence is achieved when the digits of
and
agree to as many decimal places as you desire.


Because
and
agree to six decimal places. we can say that an estimate for
.
You can compare with the value that WolframAlpha gives you which is
you can see that it agrees to six decimal places.

WolframAlpha gives you 
Answer:
-168
Step-by-step explanation:
14(5−11)(2)
=(14)(−6)(2)
=(−84)(2)
=−168
Plug the number for the x value and then solve the equation.
Exterior Angles Theorem is used.
The exterior angle of a triangle is equal to the 2 opposite interior angles.
Therefore, 65+78=143°, since 65 and 78 are the 2 opposite interior angles.
So, the answer is 143°
