Answer:
2.786.23 cubic units
Step-by-step explanation:
The volume of a full sphere is given by formula [tex](4/3)\pi r^3[/tex]
where r is the radius of full sphere.
Since hemisphere is half of full sphere , its volume is also half of full sphere which can be given by
[tex]{(4/3)\pi r^3)/2}\\=> (2/3)\pi r^3[/tex]
_____________________________________
Given radius of hemisphere in the problem = 11
Thus volume of hemisphere is
= [tex](2/3)\pi 11^3\\=>(2/3)\pi *1331\\=> 2/3*3.14*1331\\=>2,786.22667[/tex]
Thus, volume of hemisphere is 2.786.22667 cubic units
It is given that value should be rounded to tenths
So, volume of hemisphere is 2.786.23 cubic units rounded to tenth.
