Answer:
So we know the formula to calculate the area of the circular sector:
S=(r^2*π*a)/306°=
(5^2*3.14*40°)/360°= (1000*3.14) /360=8.72cm^2 so the right alternative should be the first one ,A.
Step-by-step explanation:
r - radius of the circle
a - corner of the circular sector
S - surface
15+(10-x)=15 would be your equation if that is what you are looking for.
Answer:
Step-by-step explanation:
hello:
D. (9,13) because when x=9 so y=9+4 = 13.....(right)
$2.25x+$3.50=$35
so, $35-$3.50=$31.50
Then you divide $31.50 by $2.25
That equals 14
So, x=14
There are to be exact only 2 ways to answer this equation because of the way math was made.
