Answer:
DV/dt = 942 cm³/sec (decreasing )
Step-by-step explanation:
Volume of the sphere V = 4/3π*r³
r ⇒ r(t)
DV/ dt = DV/dr * Dr/dt so
DV/dt = 4*π*r²*Dr/dt
and we know Dr/dt = - 3 cm/sec and r = 5 cm
Then radius decreasing V also decreases
by substitution
DV/dt = - 4*π*(5)²* (3)
DV/dt = - 942 cm³/sec

Answer:
The total amount of floor space in the building is
Step-by-step explanation:
we know that
A building has 217 floors. Each floor has 505 square feet of floor space
so
To find out the total amount of floor space in the building, multiply the area of one floor by the number of floors of the building
Let
x ------> area of one floor of the building in square feet
y -----> number of floors of the building
z -----> the total amount of floor space in the building in square feet
we have
substitute
