Answer: 2.73 cm
Step-by-step explanation:
Given that :
Side (a) of cube = 4.4cm
Volume of a cube (V) = a^3
V = 4.4^3
V = 85.184cm^3
Therefore, volume of the sphere made = 85.184cm^3
Volume of sphere = 4/3 πr^3
Where r = radius
85.184 = (4/3)*(22/7)*r^3
85.184 = (88/21)*r^3
85.184 = 4.1905 * r^3
r^3 = 85.184 / 4.1905
r^3 = 20.327884
Take the cube root of both sides
r = 2.73 cm
Answer: 500
Step-by-step explanation:
it is closest and is under 550. if it were 551 through 599 it would be 600
50times per turn 50x2=100:P this is a very lucky guy

Answer:
x = 0, y = 1.333, z = -1.667 ( to the nearest thousandth).
Step-by-step explanation:
2x – 3y - 9z = 11 A
3x + 3z= – 5 B
-3x + y - 4z = 8 C
Multiply Equation C by 3:
-9x + 3y - 12z = 24 D
Adding A + D:
-7x - 21z = 35 Divide by 7:
-x - 3z = 5 E
Adding B + E:
2x = 0
x = 0
Plugging in x = 0 into equation B:
3(0) + 3z = -5
z = -5/3
z = -1 .667
Now plugging the values of y and z into equation A:
2(0) - 3y - 9(-5/3) = 11
-3y = 0 + 11 + 9(-5/3) = -4
y = 4/3 = 1.333.
