X+y=155. Y= -x+155
1.50x +4(-x+155)= 520
1.50x-4x+620=520
-2.5x =-100
X= 40. Y=110
Answer:
9pi approximately 28
Step-by-step explanation:
we have the formula - pi r^2
which we know the diameter is 6 m and the surface is a semi circle
the radius is 3 so then we have pi 3^2
which becomes 9pi which is about 28.2
rounding to 28
hope this helps!!
