Volume of a cylinder: V = π * r² * h,
Base surface area of a cylinder: A_b = 2 * π * r²,
Lateral surface area of a cylinder: A_l = 2 * π * r * h,
Total surface area of a cylinder: A = A_b + A_l,
Longest diagonal of a cylinder: d² = 4 * r² + h²,
Surface-area-to-volume ratio of a cylinder: SA:V = A / V = 2 * (r + h) / (r * h)
Answer:
Step-by-step explanation:
Let X be the number of units produced, and P be the cost of production.
#Given that 
Cost of production can be calculated as:
#Mean of the total cost is calculated as;
Hence, the mean cost of production is $2,000
#Variance of the total cost is calculated as;
Hence, the variancecost of production is $3,600
Relevance Best Answer: <span>Something is wrong with the question.
$78 / 612 hours ≈ $0.13 per hour (in other words, less than 13 *cents* per hour).
To figure the hourly rate, take the total pay and divide by the hours.
For example, if it was $78 for *6* hours, it would be:
78 / 6 = $13 per hour.
Or more likely, it was $78 for *6½* hours:
78 / 6½
= 78 / 13/2
= 78 x 2/13
= 78/13 x 2
= 6 x 2
= $12 per hour</span>
So,
If you mean "speed per hour," then we just have to double the numerator of the fraction.
4 * 2 = 8
The object's speed is 8/5 miles per hour or 1.6 mph.
