Given radius=2r
Volume of sphere=4/3pier^3
=4/3pie(2r)^3
=4/3pie8r^3
=32pier^3/3
The degree is 3
90-m^0
2pier(h+r)
p(2)=4(2)^2-10(2)+4
p(2)=4(4)-20+4
p(2)=16-16
p(2)=0
As in triangle the sum of angles add up to 180
52+43+x=180
95+x=180
x=180-95
x=85
TSA of cube=6a^2
96=6a^2
96/6=a^2
16=a^2
a=4 cm
Therefore volume of the cube=a^3
=4^3
=64cm^3 is the answer
