The surface area of the drum is 3317.5218 square inches.
Step-by-step explanation:
Drum's have a cylindrical form, therefore in order to calculate its surface area we need to apply the correct formula, as shown below:
Where the first term of the sum is the area of the lid and bottom of the drum and the second term is the area of the walls of the drum, r is the radius and h is the height. Applying the data from the problem, we have:
The surface area of the drum is 3317.5218 square inches.
No Alan did not break even
Alan incured a loss of 6.25 %
<em><u>Solution:</u></em>
Given that,
Alan bought two bikes
He sold one to Beth for $300 taking a 25% loss
He also sold one to Greta for $300 making a 25% profit
When a person sells two similar items, one at a gain of say x%, and the other at a loss of x%, then the seller always incurs a loss
Which is given as:
Here, x = 25
Thus the loss percentage is 6.25 %
