Answer:
C = 12.6 inches
Step-by-step explanation:
The circumference of a circle is given by
C = 2* pi*r
Using 3.14 for pi and 2 for r
C = 2 * 3.14 *2
C =12.56
To the nearest tenth
C = 12.6 inches
You want to cover 56 inches, 8*7=56. It will cost $70 to cover the book.
X^2 - 7x = 0
Factoring:-
x(x - 7) = 0
x = 0' x - 7 = 0 so x = 7
Solution is 0, 7.
