The volume of the sphere is expressed in the formula V = 4/3 pi r^3. The rate of change of volume is determined by differentiating the formula: dV/dt = 4pi r^2 dr/dt. When we substitute 500 cm3/min as dV/dt and 30 cm as r. Then dr/dt is equal to 0.0442 cm/min
42. Because you separate 6 and 7. and 6 can be broken into 2 and 3. SO 2 times 3 times 7.

Answer:
x=14.4
Step-by-step explanation:
We apply the Sine Rule to solve for x:
#We first determine the acute angles of the larger right angles.

The smaller right angles shares one acute angle of 53.13°.
Therefore the x can be solved applying the Sine Rule again:

Hence, the length of x is 14.4
