Assuming R and H:
So volume is pir^2 * H = 1500 and H = 1500/(pir^2) while surface area is A= 2pir*H + 2pir^2
A = 2pir(r+h)= 2piR^2 + 2pir*1500/(pir^2)= 2piR^2 + 3000/r
For A to take minimum, get the derivative 4pir - 3000/R^2 and let it be 0
4pir^3 - 3000 = 0
r = cbrt(3000/(4pi)) ≈ 6.20
h = 1500/(pi(6.20)^2) ≈ 12.42
Answer:
25%
Step-by-step explanation:
so out of 32 marbles, 8 of them are red. This means the rest are blue which is 24 blue. To make a percentage, all you do is make a fraction. out of 32, 8 were red so 8/32. Fractions are basically division so 8/32 is 0.25. This means 25%.
I gallon of water per 1 inch of fish
lemon tetra is 2 inches long
so 1 lemon tetra for 2 gallons of water
20/2 = 10
they can have 10 of them
equation would be X = 20/2
Answer:
The equation of the line is:
Therefore, option a is the correct answer.
Step-by-step explanation:
Given the points
Finding the slope
As the point-slope form of the equation of the line is
where m is the slope
substituting the values and the point (-2, 2)
∵
Add 2 to both sides
Hence, the equation of the line is:
Therefore, option a is the correct answer.
