4 r1 ² π : 4 r2² π = 4 : 9
r1² : r2² = 4 : 9
r1 : r2 = 2 : 3
r2 = 3 r1/2 ( r - radius of the smaller sphere )
10 π = 4/3 r³ π + 4/3 ( 3 r/2 ) ³ π / : π/3
30 = 4 r³ + 4 * 27 r³/8
30 = 4 r³ + 27 r³/2 / * 2
60 = 35 r³
r³ = 60 / 35 = 12/7
V ( Smaller ) = 4/3 r³ π = 4/3 * 12 / 7 π = 16/7 π = 2.286 π cubic units
Answer: A. 1.01 Same as 1 1/100 fractions are rational
B. 57 Integers are rational. (Invisible implied denominator is 1)
Step-by-step explanation: c might be, but the denominator is not specified-- or maybe / is supposed to mean square root. So probably not.
D. NO, non-repeating decimal numbers are irrational

Answer:
40
Step-by-step explanation:
8: 8, 16, 24, 32, 40
5: 5, 10, 15, 20, 25, 30, 35, 40
They have 40 in common so that's the lcd.
