Step-by-step explanation:
see the attached figure to better understand the problem
step 1
we know that
The Perimeter of the square is equal to

where
a is the length side of the square

so


so
Each side of the square has a length of 10 in
step 2
Find the circumference of the circle
The diameter of the circle is equal to the length of the side of the square
The circumference is equal to

we have

substitute

step 3
Find the difference

Answer:
15 Kg cm²
Step-by-step explanation:
Given that V varies inversely with P then the equation relating them is
V =
← k is the constant of variation
To find k use the condition
V = 360, P = 20, then
360 =
( multiply both sides by 20 )
k = 7200
V =
← equation of variation
When V = 480, then
480 =
( multiply both sides by P )
480P = 7200 ( divide both sides by 480 )
P = 15
Replace all the x values with -3
f(-3)=-2(-3)^2+5(-3)
f(-3)=2(9)-15
f(-3)=18-15
f(-3)=3
