The sign should be changed as well
Hello!
The cylinder shown has a lateral surface area of about 80 square inches. Which answer is closest to the height of the cylinder? Use 3.14 to approximate pi.
We have the following data:
Al (lateral surface area) = 80 in²
R (ratio) = 4 in
h (height) = ? (in inches)
Adopt : π ≈ 3.14
We apply the data to the formula, we have:






Answer:
≈ 3.2 inches

C is your answer, you tell without solving
Answer:
u = -21/5 = -4.200
Step-by-step explanation:
Solve : 5u+21 = 0
Subtract 21 from both sides of the equation :
5u = -21
Divide both sides of the equation by 5:
u = -21/5 = -4.200
One solution was found :
u = -21/5 = -4.200
:)
(298).(100)/(440) = 67.727272....
So the answer is about 68%
