Well there can be two different solutions for this but i will choose the easier one. Obviously one requires a system of equations which obviously will involve a lot of thinking and some good algebra solving in order for them to solve.
As for hit and trial it is very easy, we can just keep adding the distance as we know they are in different directions. 450 + 550 = 1000. So 1000 x 4 = 4000 miles. So after around 4 hours they will be 4000 miles apart if they continue at the same pace.
First you need to find the radius. To do that you need to divide the diameter by two;
45 / 2 = 22.5
Then you plug the radius in the formula for a sphere. Which is...
V = (4 / 3)πr^3
First you need to find the volume with out pi
V = (4/3) π (45)^3
V= π (4/3) (91,125)
Your answer with out pi is...
V= (68,343.75) π cm^3
And with pi is...
V = 214,708.22 cm^3
the answer is c.
sin is 18/30 -------- opposite over hypotenuse
cos is 24/30 ------- adjacent over hypotenuse
tan is 18/24 -------- opposite over adjacent
