If the cone has the same width with the cup, the height of the cone will be 6 inches.
<h3>How to find the volume of cylinder and cone?</h3>
The cup is cylindrical.
Therefore,
volume of the cup = πr²h
where
Hence,
volume of the cup = π × 1.5² × 2 = 4.5π
If the cone has the same width of the cup, the height of the cone can be calculated as follows;
4.5π  = 1  /3 πr²h
4.5π = 1 / 3 × π × 1.5² × h
4.5π = 0.75πh
h = 4.5π / 0.75π
h = 6 inches

Answer:
128 and 74.
Step-by-step explanation:
128 rounded to the nearest ten is 130, and 74 rounded to the nearest ten is 70. 130-70=60

Answer:
 9/2π cm/s
Step-by-step explanation:
Volume of the spherical balloon V= 4/3πr³
Rate of change of volume dV/dt = dV/dr * dr/dt
dV/dr = 3(4/3πr²)
dV/dr = 4πr²
dV/dr = 4π(2)²
dV/dr = 16π
If V = 72cm²/s
72 = 16π*dr/dt
dr/dt = 72/16π
dr/dt = 9/2π cm/s
Hence the radius is changing at  9/2π cm/s
