Volume of Sphere=4/3.pi.r^3
Volume of Cone=1/3.pi.r^2.h
4/3.pi.r^3=1/3.pi.r^2.h
4.r=h
I = √-1
This means that i^2 = -1
If you square i until the 9th power, you will realize that i^9 = 1, or simply i.
So, your answer is i^9 = i.
18 students are 100%-37,5%-40%=22,5%
18 students - 22,5%
x students - 100%
22,5x=18×100
