Answer:
Step-by-step explanation:
r = 7 cm
h = 15cm
pi = 3.14
Top and bottom (These questions drive you crazy when you don't know if there is both a top and bottom).
Area = 2* pi *r^2 = 2 * 3.14 * 7^2
Area = 2 * 3.14 * 49
Area = 307.72 Don't round this.
Cylinder body
Cylinder body = Circumference * h = 2*pi * r * h
Cylinder body = 2* 3.14 * 7 * 15
Cylinder body = <u> 659.4</u>

Total = 967.12
Rounded 967.1 Answer
You forgot the 1/2 Inches in that,
but the answer is 45 feet.
You would use them when you are comparing something
Check the picture below.
notice, is just a 6x6 square, therefore its diagonals will cut each other in half, thus they both will meet at their midpoint, so let's check the midpoint for AC then,
