What is the rate of change of the volume of the cylinder at that instance (in cubic kilometers per second)?

Kay [80]

Answer:

hello your question is incomplete attached below is the complete question

answer : -2400 π

Step-by-step explanation:

dr/dt = -12 km/s

h = 2.5 km

r = 40 km at some instant

hence the rate of change of Volume of cylinder at that instance

= dv / dt = $d(\pi r^h ) / dt$

= $\pi h\frac{d(r^2)}{dt}$ = $-\pi h *2r *dr/dt$

hence ; dv / dt = -2400 π

What is the area of a rectangle with side lengths 2/5 feet and 4/6 feet?

kotegsom [21]

Answer:

$\frac{4}{15}$ (4/15)

Step-by-step explanation:

$\frac{4}{6}=\frac{2}{3}$

$\frac{2}{5}*\frac{2}{3};$

1- Multiply the numerators:

$2*2=4$

2- Multiply the denominators:

$5*3=15$
