Cost of aluminum required to make a ball of radius 7.5 inches is $ 161.71
<h3><u>Solution:</u></h3>
Given that
Goran's company makes solid balls out of scrap metal for various industrial uses.
For one project, he must make aluminum balls that have a radius of 7.5 inches.
Cost of aluminum = $0.12 per cubic inches
Need to determine cost of aluminum to make one ball.
Lets first calculate the volume of one ball
As shape of the ball is sphere
, we can use volume of sphere formula

Where "r" is the raius of ball
Given that radius of required ball = 7.5 inches


So quantity of aluminum required is same as volume of ball = 1347.5833 cubic inches
Cost of aluminum for 1 cubic inch = $0.12
<em><u>So cost of aluminum required to make a ball of aluminium of 1347.5833 cubic inches is given as:</u></em>

Answer:
6 quarts = 192 ounces
Step-by-step explanation:
If one quart is equal to 32 fluid ounces, how much is 6 quarts equal to?
to find out, multiply the number of fluid ounces that one quart has (32) by the number of quarts you want to find in ounces (in this case 6 quarts)
6*32= 192
6 quarts =192 ounces
Answer:
Coupon A is less than B with a difference of $3.95
Step-by-step explanation:
Coupon A: 35% of 97 33.95 and since it is a discount, you take the 35% off the 97 which is 97-33.95=63.05
Coupon B: you have 30 discount, so you just take the 30 off 97, which is 97-30=67
Coupon B has a higher price. to get the difference, you take 63.05 off 67, so 67-63.05=3.95
