Answer:
b
Step-by-step explanation:
The volume (V) of a sphere is calculated as
V = πr³ ( r is the radius )
Given V = π , then
πr³ =
π ( multiply both sides by 3 to clear the fractions )
4πr³ = 32π ( divide both sides by 4π )
r³ = 8 ( take cube root of both sides )
r = = 2
let's bear in mind that
standard form for a linear equation means
• all coefficients must be integers, no fractions
• only the constant on the right-hand-side
• all variables on the left-hand-side, sorted
• "x" must not have a negative coefficient
so, let's do away with the denominators by multiplying both sides by the LCD of all fractions, in this case 6.
