The formula for the surface area of a cylinder is pi×2rh+2pi(r^2)
In this problem, r is 4 in and h is 16 in
Answer: 16 questions
Step-by-step explanation:
To find how many problems the student correctly answered on the test, we can turn 80% into a fraction.

The student answered 16 questions correctly.
The value of (0.3)^4 is 0.0081.
Unless you mean 0.3*4, then it is 1.2.
The ratio of areas is the square of the scale factor, so that factor is
√(320/180) = 4/3
This are a few of Rational numbers are not whole numbers: 8,−3,32,7−5.
Step-by-step explanation: Hope this helps
