There are some area calculators on google if you need but I will try work it out..... if I don’t know I won’t send another answer
30b + 100u = 900
5b + 25u = 200....multiply by -6
------------------
30b + 100u = 900
-30b - 150u = - 1200 (result of multiplying by -6)
------------------add
-50u = - 300
u = 6 <== upgrated phones sold
30b + 100u = 900
30b + 100(6) = 900
30b + 600 = 900
30b = 900 - 600
30b = 300
b = 10 <== basic phones sold

( multiply each part by 12 , the LCM of 2, 3, 12 to clear the fractions )
= 6 : 3 : 1
Well, that means that the sides and top are toutching the sphere
radius of sphere=10 so radius of cylinder=10
the height is the diameter or 20
V=hpir^2
v=20pi10^2
v=20pi100
v=2000pi
answer is D
