The volume of the global hemisphere is Find its diameter.
The volume of the global hemisphere is \( 19404 i n^{3} . \) Find its diameter.
- A. 21 in
- B. 42 in
- C. 10.5 in
- D. 9 in
Step-by-step solution
Volume of hemisphere = (2/3)πr^3 = 19404. Solving gives r^3 = 29106/π ≈ 9261, so r ≈ 21 in. Diameter = 2r = 42 in.
