Answer:
the question isnt clear
Step-by-step explanation:
Surface area of the cylinder = 816.4 sq. ft.
Solution:
Height of the cylinder = 21 ft
Diameter of the cylinder = 10 ft
Radius of the cylinder = 10 ÷ 2 = 5 ft
Use the value of = 3.14
Surface area of the cylinder =
Substitute the given values in the surface area formula, we get
Surface area of the cylinder
ft²
Hence the surface area of the cylinder is 816.4 sq. ft.
Initial velocity of John's car (V1) = 0 miles per hour
Final velocity of John's car (V2) = 45 miles per hour
Time taken for acceleration = 45 seconds
Then
Acceleration = (V2 - V1)/Time taken
= (45 - 0)/15 miles per hour per second
= 45/15 miles per hour per second
= 3 miles per hour per second.
So the approximate rate of change in the miles per hour that John's car accelerated is 3 miles per hour per second. The correct option among all the options given in the question is option "A".
