Use your keyboard and if that doesn’t work on the right top comet there’s a pen that should work :))
A. for the circumference it is C=pi(d)=pi(2r)=pi(10)= 31.4 ft
b. for the area it is A=pi(r)^2=pi(5)^2=pi(25)= 78.5 ft squared
c. since the are is 78.5 ft squared multiply by $4.50= $353.25 to floor the circle.

Answer:
C
Step-by-step explanation:
16 ounces is equal to 1 pound
Divide 54 by 16 and you get 3.375
You know that there are 3 pounds now, so subtract 3 from what you got to get 0.375
Now multiply 0.375 by 16 to turn it back into ounces, which is 6
3 pounds and 6 ounces is answer choice C
Answer:
.
Step-by-step explanation:
We want to convert the function into the form that let's us easily find the x-intercept, and it would be for the form 
because then we can find the x-intercept in the following manner:
We factor our function 
and get
Now this form let's us easily find the x-intercepts:
and so we pick the second choice: f(x)=(2x+1)(2x-1).
