The formula for a come is V=πr^2h/3.
<u>ANSWER</u>
<u>EXPLANATION</u>
The given series
This is an arithmetic series with a common difference of
The first term of the series is:
The general term is given by:
The last term is 81
We can use this to determine the number of terms in the series.
The summation notation is:
Answer:
22 pi ft
Step-by-step explanation:
We can use the area to find the radius
A = pi r^2
121 pi = pi r^2
Divide each side by pi
121 = r^2
Take the square root
sqrt(121) = sqrt(r^2)
11= r
Now we need to find the circumference
C = 2*pi*r
C = 2* pi *11
C = 22 pi ft
Answer:
3x - 4
Step-by-step explanation:
Difference means subtraction.
Times means multiplication.
Three times a number x; 3 * x = 3x
3x - 4
Best of Luck!
