the volume of a cylinder is 411π in^3. The height of the cylinder is 9 in. Calculate the diameter of the cylinder to the nearest
EleoNora [17]

Answer:

13.5 in, or 34.3 cm.

Step-by-step explanation:

First, use the formula volume = pi * r^2 * height- you have the volume, so just solve the equation 411pi = pi * 9 * r^2 for r, and you get that r = 6.75. Since diameter is equal to 2r, multiply 6.75 by 2 to get your answer of 13.5 inches. The questions asks for the diameter in centimeters though, which makes it 34.3 cm.

Hopefully this helps- let me know if you have any questions!

Katen [24]

She wants to serve --------- >  2 gallons of juice that is 75% orange juice and 25% pineapple juice

then 

2*0.75------------------ > 1.5 gallons of orange juice

2*0.25------------------ > 0.5 gallons of pineapple juice


2 gallons------------ >1.5 gallons of orange juice+ 0.5 gallons of pineapple juice

if 1 gallons pineapple juice mixture--------------------- > 0.40 gallons pineapple juice

X------------------------------------------------------------------- > 0.50 gallons pineapple juice

X=50/40=1.25 gallons juice mixture

1.25 mixture gallons---- > 0.50 gallons pineapple juice+0.75 gallons orange juice

Therefore

(2-1.25)=0.75 gallons of orange juice

2 gallons------------ >0.75 gallons of orange juice+ <span>1.25 mixture gallons  </span>

0.75*(p)+1.25*(m)=2--------------- > (0.75/1.25)*(p)+(1.25/1.25)*m=2/1.25

0.60p+m=1.6

 The answer is 0.60p+m=1.6

16n2 – 10n – 5 = 6n<br> Solve the equation for all real solutions
sergiy2304 [10]

Answer:

n=5/4 or n=-1/4

Step-by-step explanation:

16n^2 - 10n-5=6n

16n^2-16n-5=0

(4n)^2-2.4n.2+2^2 = 2^2 + 5

(4n- 2)^2=9

4n-2 = 3 or 4n-2=-3

4n=5 or 4n=-1

n=5/4 or n = - 1/4
