The answer is 7.85
First, you divide the diameter by two to get the radius (2.5) and then you multiply by pi(3.14) to get 7.85
I am sorry but this cannot be put as a mixed number. The answer is 11. To dot his do 11/3 divided by 2/6 u would first do same change flip and do 11/3 times 6/2 which then u would multiply straight across and u would get 66/6 which equals 11 because 66 divided by 6 equals 11. I hope this helped u! ;)
The equation that matches the given points is g(x) = -1.4x + 7.6
The standard form of a linear equation is expressed as 
- m is the slope of the line
Using the coordinate points (3, 3.4), (4,2)

Substitute m = -1.4 and the coordinate (4, 2) into the formula:

Get the required equation:

Hence the equation that matches the given points is g(x) = -1.4x + 7.6

Im pretty sure it is the first one
There are 64 boys in the class because 24/3=8 and you have to do the same thing so 8 times 8= 64
