Answer:
4b
Step-by-step explanation:
that's the correct answer
Two angles are coterminal if they differentiate in a factor of k*(2pi). This is a multiple of 360 degrees.
In this case 21 [pi /10] = [pi / 10] + 20 [pi/10] = [pi/10] + 2pi, then 21pi/10 is coterminal with pi/10.
In the case of -pi/10 you cannot get to pi/10 by adding a multiple of 2pi , then they are not coternminals.
Conclusion: you would not be right.
The volume is nine wholes and 3/4 or 9 3/4
The nearest when you round it would be to the closest is 24.2 m i think dont no for sure but i;m gonna go with that answer
