The formula for the area of a circle is:
π*radius^2
Input the information we already know:
π*5^2
Follow BEDMAS
π*25
=78.5398163
Since half of the circle is shaded, divide the area by 2
78.5398163/2
=39.2699081
The area of the shaded sector is 39.2699081 meters²
Answer: y= -1
Step-by-step explanation:
Add 5 to both sides,
y-5+5=-9y-15+5
Simplify,
y=-9y-10
Add 9y to both sides,
y+9y=-9y-10+9y
Simplify,
10y=-10
Divide both sides by ten.
10y over 10 = -10 over 10
There you go!
The answer would be -6 if the “-“ next to the second three is a subtraction sign

Answer:
$98.15
Step-by-step explanation:
2005 is 15 years after 1990. Using the formula we find ...
c(15) = 63·1.03^15 ≈ 63·1.55797
c(15) ≈ 98.152
An ounce of the chemical costs about $98.15 in 2005.
