The least consistent would be A i think, not for sure
Answer:
Step-by-step explanation:
a = - 4
b = 10
c = - 8
The discriminate is
D = b^2 - 4ac
D = 10^2 - 4*(-4)(-8)
D = 100 - 128
D = - 28 which is not a nice number
Because the Discriminate has a minus result, there are no real zeros.
Radius = cube root (sphere volume * .75 / PI)radius = cube root (33.5 * .75 / PI)radius = cube root (

Step-by-step explanation:
D=9
A=pie*radius^2
=3.14*9/2*9/2
=63.58
=64
The height is 4 feet. You calculate the area by length times height. So what multiplied by 15 is 60? Well, 15ft x 4ft = 60ft^2
