The radius of a circle is decreasing at a rate of 6.56.56, point, 5 meters per minute. At a certain instant, the radius is 121212 meters. What is the rate of change of the area of the circle at that instant (in square meters per minute)

The rate of change of the area of the circle is  approximately .

Step-by-step explanation:

Given:

radius

We need to find the rate of change of the area of the circle at that instant.

Solution:

Now we know that;

Area of the circle is given by π times square of the radius.

framing in equation form we get;

to find the rate of change of the area of the circle at that instant we need to take the derivative on both side.

Substituting the given values we get;

Hence The rate of change of the area of the circle is  approximately .

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
