<span>I have been a high school/jr high math teacher for the past 13 years. I am happy to explain how to proceed with this problem.
A square is a figure where ALL sides are exactly the same. The find the area of the square you would multiply one side times another side. You would be multiplying a number times itself. So if you already have the area, you would take the square root to find your answer. When you do, you end up with 21.21 square inches rounded to the nearest hundredth.</span>
Answer:
the dimension that will minimize cost are radius of 2.79 inch and height of cylinder of 1.40 inch.
Step-by-step explanation:
volume of a circular cylinder = πr²h
volume of 19 fluid ounces (1 fluid ounce is approximately 1.80469 cubic inches) = 19* 1.80469 =34.28911 in³
The cost per square inch of constructing the top and bottom is twice the cost of constructing the lateral side, means
surface area of top + bottom = surface area of side
area of circle(top + bottom) = πr²+πr² = 2πr²
area of the side = 2πrh
the cost of top and bottom = twice the cost of side
2πr² = 2( 2πrh) = 4πrh
divide both side by 2πr
r= 4πrh/ 2πr =2h
r = 2h
for volume = πr²h = 34.28911 in³
and r = 2h
π(2h)²h =34.28911 in³
4πh³ = 34.28911 in³
h³ = 34.28911 /(4*3.142) = 2.7283 in³
h = cube root of 2.7283 in³ = 1.397 inch
r = 2* 1.76 = 2.794 inch
the dimension that will minimize cost are radius of 2.79 inch and height of cylinder of 1.40 inch.
Answer:
762.5
Step-by-step explanation:
25% of 610 is 152.5 and 610 + 152.5 is 762.5
Hope this helped also can i get brainliest?

Answer: x =104
Step-by-step explanation:
If we draw the black line shown in the figure, two isosceles triangles are formed, and the base angles of the isosceles triangles are the same. The red angles are the same and the green ones too. The 104 degree angle is the sum of the red angle and the green angle, and x is also the sum of the red angle and the green angle, therefore x = 104.
