Answer:
12.4 cm
Step-by-step explanation:
Use the sphere volume formula, V = r³
Plug in the volume and solve for r, the radius:
V = r³
7961 = r³
1900.55 = r³
12.39 = r
So, the radius of the sphere is approximately 12.4 cm
3x - 1 = 3x + 1
subtract 3x from both sides to get (-1 = 1). This is a false statement so it is: CONTRADICTION
************************************************
4x - 11 = 7
add 11 to both sides and then divide both sides by 4 to get . This statement is true only when x =
so it is: CONDITIONAL
*************************************************
2 - 8x = 2 - 8x
add 8x to both sides to get (2 = 2). This is a true statement so it is: IDENTITY
*************************************************
x + 1 = -x + 4
add x to both sides, subtract 1 from both sides, and divide both sides by 2 to get . This statement is true only when x =
so it is: CONDITIONAL
