Surface Area = 2πr² + 2πrh
Surface Area = 2π(7)² + 2π(7)(15) = 308π in²²
Answer: 308π in²
The equation that show the relationship between Anna earning and time worked is y = 8.5h.
<h3>
Linear equation</h3>
Linear equation is in the form:
y = mx + b
where m is the rate of change, b is the y intercept and y, x are variables.
Let y represent Anna earnings for working h hours.
Since she charges $8.50 per hour to babysit. Hence:
y = 8.5h
The equation that show the relationship between Anna earning and time worked is y = 8.5h.

Step-by-step explanation:
A=2πrh+2πr2=2·π·3·6+2·π·32≈169.646
The correct answer is 3: 35
Explanation:
To calculate at what time Jenny will arrive in Rochefort, the first step is to calculate the approximate time of the trip. Now, to calculate this consider the time of a movement (t) equals to the distance (d) divided by the speed (s), the process is shown below:
t = 483 km / 84 km/h
t = 5.75 hours
In this number 5 refers to the hours and 0.75 represents 45 minutes considering 0.75 x 60 minutes in one hour = 45 minutes. Therefore, the total time from Paris to Rochefort is 5 hours and 45 minutes. Now, to calculate the time of arrival add this result to the time of departure.
Add the hours: 5 hours + 9 hours: 14 hours
Add the minutes: 50 minutes + 45 minutes =95 minutes
95 minutes are equivalent to 1 hour (60) minutes and 35 minutes
Calculate the total
Hours: 14 hours + 1 hour = 15 hours or 3 in the 12 hour system (15 hours - 12 hours = 3 p.m.)
Minutes: 35 minutes
