If the 8 parts are all exactly the same size,
then the shaded portion is 3/8 of the circle.
To change any fraction to a decimal, do the division:
(3) divided by (8) = 0.375 .
To change any decimal to a percentage,
move the decimal point two places that ==> way.
0.375 = 37.5 %
Answer:$58.50
Step-by-step explanation:
The price was 130
With 40% off
Which reads out in this format
40/100*130= 52 dollars off the real price
130-52=78 dollars
Then later reduce by 25 percent
Now the price is 78 dollars
25/100*78= 19.5 dollar off the new price
So the real price will be
78-19.5=$58.5
Plug in 8 for c and -3 for d
(8)^2+(-3)^3
Evaluate exponents
64+ (-27)
Add the two terms
37
Final answer: 37
Answer: 18 cm
Step-by-step explanation:
We know the circumference formula is C=2πr. Since our circumference is given in terms of π, we can easily figure out what the radius is.
36π=2πr [divide both sides by π to cancel out]
36=2r [divide both sides by 2]
r=18 cm
