The surface area of a cylinder is the sum of the top + bottom + body, right?
The top and the bottom are circles with the same radius 3.5 . And we know that the area of a circle is r^2pi, (don't forget we have 2 circle, so, the answer must be multiplied by 2)
Now, the body: the body is just a rectangular with the width is the height of the cylinder and the length is the circumference of the circle.
The circumference = 2 r pi
the height is given
All you need to do is to calculate them and add them up. You need to work out to get the answer.
Answer: 50 Books
Step-by-step explanation:
B = number of books in Ruben's collection BEFORE he bought new ones.
So 6 books were bought which increased his collection by 12%.
12% as a decimal would be 0.12..then we add the variable which represents the number of books, 0.12B.
So then we know 0.12=6
*We need to isolate the variable* So we would divide 0.12 on both sides. 0.12/0.12 and 0.12/6 which is 50.
Hope this helps! :)
