Answer: The answer is (C) 1.61.
Step-by-step explanation: Given that the volume of a sphere is equal to the volume of a cube. We are to find the ratio of the edge of the cube to the radius of the sphere.
Let, 'r' be the radius of the sphere and 'e' be the edge of the cube. Then, the volume of the sphere is given by

and the volume of the cube is

According to the question, we have

Thus, the correct option is (C) 1.61.
Answer:D
Step-by-step explanation:
-9+9=0
First step is square root both sides leaving with
x-6=+/-3
closest one is A
answer is A
add the two equations together
5a+5b=25
-5a+5b=35
------------------
0 + 10b =60
divide by 10
b=6
5a + 5b = 25
5a +5(6) = 25
5a +30 =25
subtract 30 from each side
5a =-5
divide by 5
a = -1
Answer (-1,6)
or a=-1 b=6
