r is the radius and in this case its 18.
4/3 times
times 18^3
4/3 times 5832 times 
4 times 1944 times 
7776 times 
The volume of the sphere is 7776
Answer:
m<2 is 45° because there is proof in the problem.
m<1 is 45°, and m<1 is equal to m<2, so m<2 equals 45°
Hope this helps!
The answer is 1/3x + 2/4 .
