Answer:
132.7495 cm^2
Step-by-step explanation:
area of circle=πr^2
radius=6.5
6.5^2
42.25
42.25*3.142
132.7495
40 liters.....30% is yellow tint
0.30(40) = 12 liters are yellow
if u add 6 liters....(12 + 6) = 18 liters are now yellow...and since u added 6 liters, ur total mixture is now 46 liters.
18/46 = 0.39 = 39% <===
(-5+8*i)+(-9+5*i) evaluates to <span>-14+13i</span>
