C = 11.6239mm
Circumference Formula is C = 2πr
R = 1/2 D
R = radius
D = diameter
π = 3.14
C = circumference
1/2 3.7 = 1.85
2 x 3.14 x 1.85 = 11.6239
Step-by-step explanation:
Will bought several books that cost $ 2.50 each and received a $ 2 discount on the total bill. If he paid $ 10.50, how many books did he buy ?
2.50x - 2.00 = 10.50
2.50x = 10.50 + 2.00
2.50x = 12.50
x = 12.50/2.50
x = 5....he bought 5 books
The answer is 26/7 it may seem to small to be the answer but just simplified it
