9/2=4.5
4.5*6=27
Again
1000kg = 1ton
3000kg = 3 tons
50.24 square inches. If the diameter is 8in, then the radius must be half the diameter, or 4. You can just plug 4 into the formula for the area of a circle [A=pi*radius^2]. When you multiply 3.14 by 4^2, you get 50.24 square inches.
Let e be the minimum number of workers needed.
e(100-3)/100≥215
97e/100≥215
97e≥21500
e≥21500/97
e≥221.6
Since the number of employees must be an integer...
e≥222
So the minimum number of employees needed is 222.
