the answer will be option A
Step-by-step explanation:
for the volume of a cube , we know,
(side)^3
so, here (2r)^3
= 8r^3
and the volume of a sphere is 4/3πr^3
so for a hemisphere it will be half., then 2/3πr^3
adding these two....we get
8r^3 + 2/3πr^3
= r^3(2/3π+8)
A - 7 + 3 = 0
a -4 = 0
a = 4
Answer is C
