21 students
You find this by subtracting the number of students absent from the total amount of students in the class
.
219+159≤x≤369+309
The answer can then be simplified to
378≤x≤678
Answer:
Since we have two semi-circles we can say that we have a full circle. using the circle area formula we can say that
3.14*2^2 = 12.56 cm
Using the rectangle area formula we can say that
19*4 = 76 cm
Adding them both together is
12.56 + 76 = 88.56 cm
So the bookmark has an area of 88.56cm^2
It doesnt make any sense because the diagram is wrong so I'm guessing it would be either 8 or 6. Im sorry that problem is wrong :(
