Answer:
Volume of the hemisphere = 
Step-by-step explanation:
It's a picture of a globe and a globe of the Earth is in the shape of a sphere.
We know equator divides the earth into two equal halves and these equal halves are called as "hemisphere".
Therefore, a line joining the two extreme points of the diameter of the Earth divides the Earth into two hemispheres.
If the radius of the Earth is 'r',
Volume of the hemisphere = 
Answer:
The required hypothesis to test is

. Thus the null hypotheses is shown as:

The alternative hypotheses is represents as
. Thus the alternative hypotheses is shown as:

Hence, the required hypothesis to test is
and
.
From what I think of this question, i think of 9x37 and 8x37 OR 9/37 and 8/37. either way
8x37=296
9x37=333
9/37=0.2432
8/37=0.2162
1km=1000metres
15km=15000 metres
15000/600=25
25-1=24 (minus the last one)
hope this helps :)
Uhhhhhhhhhhhhhhhhhhhhhhhh
