Answer:
6174π
Step-by-step explanation:
The equation for a whole sphere is 4/3 π(r)³
Given the diameter of 42, we can conclude that the radius would be 21
Next, we would plug in these variables and get 4/3 π(21)³
Simplify all of this down and you would get 12348π
Keep in mind that we are working with a hemisphere. That means that we need to take half of 12348π
Divide that by 2 and you get 6174π
Hope this helps! :)
