Answer:
1,115.8937105551
Step-by-step explanation:
[ π x 40² ] =5,026.5482457437
[ 80 / 360 ] ft² =[,222] ft²
5,026.5482457437 X [,222] ft²= 1,115.8937105551 ft²
A = [ π x 40² ] [ 80 / 360 ] ft²
A = 1,115.8937105551 ft²
you can round 279 to 280
3
If you divide the total cost (y) by the number of balloons (x) you get 3 for all of them
y2+4y+1=0. where, y=-2
(-2)2+4(-2)+1
-4-8+1=0
-12+1=0
-11=0
