About 84.82
Step-by-step explanation:
The formula to find the volume of a cone is pi*r^2*(h/3). The formula to find radius is diameter/2. 6/2=3. Since r=3 and h=9, pi*3^2*(9/3)=84.82
For x=1: -7 x 1 + 4 = -3 y=-3
The ordered pair:(1, -3)
for x=3: -7 x 3 + 4 = -17 y=-17
The ordered pair:(3, -17)
for x=5: -7 x 5 + 4 = -35 y=-35
The ordered pair:(5, -35)
for x=7: -7 x 7 + 4 = -45 y =-45
The ordered pair:(7, -45)
The angles will add up to 180 degrees.
