Rewrite the equation by completing the square.
dlinn [17]

Answer:

(x + 1/2)^2 =  289/4

Step-by-step explanation:

x^2+x-72=0

Write like this:

(x + ___)^2 = ___

put 72 on other side

x^2 + x  = 72

x^ + x  + (1/4) = 72  + (1/4)

(x + 1/2)^2 =  289/4

x + (1/2) =  17/2

ben is filling up his cylinder shaped pool up to 80% of its capacity . If his is 6 feet deep and has a diameter of 18 feet, how
vlada-n [284]

Answer:

You will put 1220.83ft³ of water in the pool

Step-by-step explanation:

radius = half of diameter

d = 18ft

r = 18ft / 2 = 9ft

To calculate the volume of a cylinder we have to use the following formula:

v = volume

h = height = 6ft

π = 3.14

r = radius = 9ft

v = (π * r²) * h

we replace with the known values

v = (3.14 * (9ft)²) * 6ft

v = (3.14 * 81ft²) * 6ft

v = 254.34ft² * 6ft

v = 1526.04ft³

The volume of the cylinder is 1526.04ft³

If it is filled to 80% then we have to multiply the volume by 80/100

1526.04ft³  * 80/100 = 1220.83ft³

You will put 1220.83ft³ of water in the pool
