Find the area of the following circle.
ra 9 yd.
area
square yards.

Well the formula for this problem is A=3.14(pi) * radius * radius 
So multiply 3.14 times 9 times 9. first multiply 9 with 9 you get 81 then you multiply 81 times 3.14 which equals 254.34. When you find the formula to this kinds of equations it's very easy all you have to do is plug in the numbers. Hope this helps :) 

x < 16

Step-by-step explanation:

Let the number be x

Four time the number = 4x

Eight less than four times the number = 4x - 8

Eight less than four times the number is less than 56,

          that is , 4x - 8  < 56

                      4x - 8 + 8 < 56 + 8                    [ adding both sides by 8 ]

                        4x + 0 < 64

                              4x < 64                             [ divide both sides by 4 ]

                                 x < 16
