To find the mass and volume of irregularly shaped object. One can use the balance to find the weight, and to find the volume of the object water should be poured in the beaker and note the level of water.
<span>-2,5SD = 2.1%
</span>first u need to find number of standard deviations and look up on table what percentage that is
Answer:
3.185 x 10^-3 cm/s
Explanation:
dV / dt = 4 cubic cm per second
r = 10 cm
The volume of sphere is given by
V = 4/3 x π x r³
Differentiate both sides with respect to t
dV / dt = 4/3 x π x 3r² x dr/dt
Put dV / dt = 4 cubic cm per second, r = 10 cm
4 = 4/3 x 3.14 x 3 x 10 x 10 x dr/dt
dr/dt = 3.185 x 10^-3 cm/s
