A spherical snowball is melting in such a way that its radius is decreasing at rate of 0.3 cm/min. At what rate is the volume of the snowball decreasing when the radius is 17 cm. (Note the answer is a positive number).

The volume of spherical snow ball is decreasing at a rate 1088.952 cubic cm per minute.

Step-by-step explanation:

We are given the following in the question:

The radius of a melting snowball is decreasing.

Instant radius = 17 cm

Volume of spherical snow ball =

Rate of change of volume =

Thus, the volume of spherical snow ball is decreasing at a rate 1088.952 cubic cm per minute.

except a rational number. : )

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
