Answer:
The area is changing at the point of 
Step-by-step explanation:
From the given information:
Let's recall from our previous knowledge that the formula for finding the area of a rectangle = L × w
where;
L = length and w = width of the rectangle
Suppose the Length L is twice the width w
Then L = 2w --- (1)
From The area of a rectangle
A = L × w
A = 2w × w
A = 2w²
Taking the above differentiating with respect to time

At the time t

Replacing the values back into equation 2, we get:


circumference =2πr=2× 7 22 ×28=22×8 =176 cm
Area =πr 2 = 7 22 ×28×28=88×28 =2464 cm 2
<u><em>circumference=176 cm </em></u>
<u><em>Area= 2464 cm 2</em></u>
If N and A are defined, you multiply the value of N by the value of A.
Answer:
c
Step-by-step explanation:
-b -4b - 10
-5b - 10
hence c is the answer
If that helps, but I'm pretty sure the answer is -1 that is what I have found in Google that is what all the answers are that in finding.
