Little susie is enjoying a nice spherical lollipop. she sucks the lollipop in such away that the circumference decreases by 1 centimeter per minute. how fast is the volume of herlollipop changing when the lollipop has a radius of 5 centimeters? remember to include units

-50 cm^3/min

Explanation:

The volume of the lollipop is given by

where r is the radius in centimeters.

To find how fast the volume changes, we need to find the rate of change of the volume, which is given by its derivative with respect to time:

(1)

where

dr/dt is the rate of change of the radius

We know that the circumference is

and it decreases by 1 cm per minute, so

(cm/min)

from which we find dr/dt:

Substituting into (1),

 (cm^3/min)

And substituting r = 5, we find the rate of change of the volume when the radius is 5 cm:

(cm^3/min)

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .
