D. 226.08cm^2
Since we are finding the combined area of the two bases of the cylinder, we are adding the area of the first base with the second base. The formula for the base of a cylinder is pi x r^2, since it is a circle. Since the bases are the same, we can rewrite this as 2pi x r^2.
Since the diameter is 12cm and r = 1/2 diameter, r = 6cm.
Thus, A = 2(3.1415)(6)^2 = 226.08cm^2
513 as a percentage of 900 can be re-written as;

= 57 percent
Hi there! The answer is x = 1


Rule AB = 0, gives A = 0 or B = 0

Therefore, the smallest of both roots is x = 1.
Answer:
Let the number of books she can purchase = b
The cost of each book is $5.5 with an extra shipping of $7.5
So, the total cost of the books she can purchase = 
Since, she had $65 to spend on the books.
The required inequality is
.
So, according to the inequality above, we get,
The correct options are,
B. The inequality symbol is incorrect because she can spend up to and including $65.
C. The expression
is correct because $5.50 per book is
and that is added to the shipping fee of $7.50 to determine the total purchase price.
