It is which ever one adds up to 90
If the volume of a cylinder is x, then the volume of a cone with same height and diameter is x/3
so
if the cone is 72ft³ then the cone with same base and height is 72/3ft³=24ft³
answer is A
<span> When area is equal 1120. We can write an equation
(x+4)(-x+64)=1120
-x²-4x+64x+256=1120
-x²+60x+256-1120=0
-x²+60x-864=0
D=b² - 4ac= 3600-4*864=144, √D=12
x= (-b+/-√D)/2a
x=(-60+/-12)/(-2)
x=24, x=36
For x=24
(x+4)=24+4=28
(-x+64)=(-24+64)=40
For x=36
(x+4)=36+4=40
(x-64) =(-36+64)=28
So sides should be 28 and 40 in.
We did not get any extraneous solutions. They could be if we get negative length side, for example. They can come because a quadratic equation can
give positive and negative numbers because a^2 and (-a)^2 give the same positive number.
We chose to solve this equation using formula for quadratic equations, because this equation has too big numbers to solve it using other methods.

Answer: The square root of 135 is between 11 and 12
Step-by-step explanation:
10 x 10 = 100 → too low
11 x 11 = 121 → between 121
12 × 12 = 144 → and 144
13 x 13 = 169 → too high
Therefore, the square root of 135 is between 11 and 12.
