Answer:
The answer instead is 10:14.
Step-by-step explanation:
In this case, there are ten boys and fourteen girls in this class. The ration would then be 10:14. Instead, Jeff said 5:12 which isn't correct. He can correct it by using the number of boys given, find the difference of girls in a class of twenty-four students, and then get his answer!

Answer:
1.60 
Step-by-step explanation:
Assuming that this is a cylindrical pipe, the area can be determined by applying the formula for calculating the area of a circle.
i.e Area = 

So that,
for the inner part of the pipe,
r = 
  = 
  = 2.5 feet
Area of the inner part of the pipe = 

                                  = 3.14 x 
                                  = 19.625
Are of the inner part of the pipe is 19.63  .
.
Total diameter of the pipe = 5 + 0.2
                                            = 5.2 feet
r = 
  = 2.6 feet
Area of the pipe = 

                             = 3.14 x 
                             = 21.2264
Area of the pipe is 21.23  .
.
Thus the cross sectional area = Area of the pipe - Area of the inner part of the pipe
                                            = 21.2264 - 19.625
                                            = 1.6014
The cross sectional area of the cement pipe is 1.60  .
.
