Answer:
C≈47.25
Step-by-step explanation:
Use the formula C= πd, where C is circumference, π is pi, and d is diameter.
Input the numbers and we'll shorten π to 3.15
C=3.15(15)
C≈47.25
In geometry, the circumference (from Latin circumferences, meaning "carrying around") of a circle is the (linear) distance around it. That is, the circumference would be the length of the circle The area of a circle is pi (approximately 3.14) times the radius of the circle squared.
<h2>a. 20 & 9 are the coefficients and x & y are the variables of the expression.</h2><h2>b. There are 2 terms in the expression they are 20x & 9y the reason why is because the two terms are separated by addition</h2><h2>c. The term that shows the total of every hedge that was trimmed is 9y

Answer:
-32
Step-by-step explanation:
10–{22–[(−9)+(−11)]}
Work inside out
10–{22–[(-20)]}
Subtracting a negative is adding
10–{22+20}
10 - 42
-32
