Answer:
I. 94.99 in²
II. $0.23
Step-by-step explanation:
<u>Given the following data;</u>
Diameter of wheel = 11 inches
Cost of wheel = $21.35
<em><u>Part A</u></em>
To find the area;
We know that a wheel is circular in nature. Thus, the area of a circle is given by the formula;
Substituting into the equation, we have;
<em>Area, A = 94.99 in²</em>
<em><u>Part B</u></em>
To find cost per square inch;
<u>Cost per square inch = $0.23</u>
Answer:
11.99 ft
Step-by-step explanation:
The formula for the volume of a cyl. of radius r and height h is V = πr²h.
Solving this immediately for h yields:
V
h = ----------
πr²
Inserting the known quantities results in:
V 1356.48 ft³
h = ---------- = ---------------------- Note that r = (1/2)d, so r = (1/2)(12 ft) = 6 ft
πr² 3.14159 (6 ft)²
= 11.994 ft
The height of the cyl. is 11.99 ft (to the nearest hundredth foot)

Answer:
Option C: 
Step-by-step explanation:
Given the side length of a square is 11 units.
Note that 
Since, length cannot be negative, we can eliminate - 11.
Hence, the length of the side of the square is 11 units = 
.
Hence, the answer.
