Step-by-step explanation:
The surface area of the cylinder will be 1206.37 square feet.
<h3>What is surface area?</h3>
The space occupied by any two-dimensional figure in a plane is called the area. The area of the outer surface of any body is called as the surface area.
Given that the radius of the cylinder is r = 12 ft and the length of the cylinder is 16 ft.
The volume of the cylinder is calculated as:-
V = 2πrl
V = 2 x π x 12 x 16
V = 1206.37 square feet.
Therefore the surface area of the cylinder will be 1206.37 square feet.

Answer:
90 mi/h
Step-by-step explanation:
Given,
For first 30 miles, her speed is 30 miles per hour,
Let x be her speed in miles per hour for another 30 miles,
Since, here the distance are equal in each interval,
So, the average speed of the entire journey


According to the question,



Hence, she needs to go 90 miles per hour for remaining 30 miles.
