If a snowball melts so that its surface area decreases at a rate of 5 cm2/min, find the rate at which the diameter decreases when the diameter is 11 cm.

The diameter decreases at a rate of .

Step-by-step explanation:

The surface area of a sphere is given by

and its diameter is .

We assume that the snowball is a sphere.

If we take the derivative with respect with time using the chain rule, we get:

We know that the area decreases at a rate of , and we want to find the rate at which the diameter decreases when the diameter is 11 cm

So,

The diameter decreases at a rate of .

27 + 13x + 15 = (x + 5)( =

step-by-step explanation:

27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( =

answer: 8

step-by-step explanation: if you add the possibilities 5 different flavor and 3 different sizes 5+3=8
