radius = 3 feet
rearrange the formula making r the subject
πr³ = V ( multiply both sides by 3 to eliminate fraction )
4πr³ = 3V ( divide both sides by 4π )
r³ =
= ( 3 × 36π ) / 4π = 3 × 9 = 27
take the cube root of both sides
r =
= 3
It is the first option i think

Y and the angle marked 60 degrees are internal alternate angles and are equal
so y = 60
Step-by-step explanation:
y = 23.28/6 x
y = 3.88 x
so, the constant of proportionality is 3.88
