1)V=Ixwxh

=5 cm x 3 cm x 2 cm

=30 cm³

2)V=bxh

=(10m x 6m) x 4m

= 60 m² x4 m

3)V=Ixwxh

=3 cm x 3 cm x 3 cm =27 cm³

=240 m³

The rate of change of the volume of a snowball that is melting is proportional to the surface area of the snowball. Suppose the

Alisiya [41]

Answer:

According to the passage, we have the next equation:

$\frac{dV}{dt} = \frac{4}{3}\pi*3*r^{2}*\frac{dr}{dt} = K*(4\pi*r^{2} )$

where "K" is a proportional constant

Leaving at the end with the next equation:

$\frac{dr}{dt} = K$

Integrating the equation, we have:

$r=K*t+C$

where "C" is a constant

Then, we have the 2 conditions for the problem:

1) t=0 → r=10

Replacing in the equation, we have C = 10

2) t=5 → r=8

Replacing in the equation, we have K = -0.4

Finally, the time which the snowball will be completely melted will be when r = 0. So replacing in the equation

$0=-0.4*t+10$

t = 25 minutes

The diameter of a circle is two times its radius. Which equation shows another way to represent the area of a circle?

horrorfan [7]

If the area for a circle is $A= \pi r^{2}$ , you can write it in terms of its diameter like this: $A= \pi ( \frac{1}{2}d) ^{2}$
