The formula for area of a circle is π × radius², and the radius is half of the diameter, which means that your final expression is π × 6² = 36π = 113.1 inches². I hope this helps!
Answer:
C. 27x-67
Step-by-step explanation:
To simplify, combine like terms meaning variable terms with variable terms and constants with constants.
81x-54x = 27x
-46-21=-46+-21=-67
The expression is 27x-67
Answer:
p=7/2
Step-by-step explanation:
Rember that a p series can be represented by

Here, notice that

This is true for all parts of the series because

So p=7/2
Present value, P = 10000
interest rate, i = 5.4% continuous
Number of periods, n = 8 years
Future value



to the nearest cent
We have the equation 1/2x + 200 =1200 so we know that we have 200 already as one of the numbers so 1/2 is half of x + 200 equals 1200 since we have 200 we know that 1/2 of x is going to be 1000 because 1000+200=1200 meaning x is 2000. So your answer would be x=2000 or 1/2 2000 + 200=1200
