Answer:
teczoneq:) im rlly awkward tho-
Answer:
Step-by-step explanation:
Arc length has a formula of
and we have all the info we need to solve for the radius, which we will then use in the circumference formula:
and simplifying a bit,
and a bit more,
. Multiply both sides by 9:
72π = πr . Divide both sides by π to get that
r = 72.
Now we will sub that into the circumference formula to find the circumference. Recall that C = 2πr.
C = 2π(72) so
C = 144π

Step-by-step explanation:
The area of a shape is the amount of space the shape can occupy.
The dimension that maximizes the design is 20 inches by 20 inches
From the question, we have:
Let the length and width of the graphic (without the margin) be l and w.
So, the dimension of the whole graphic is:
The area is then calculated as:
Substitute
Make l + 4, the subject
Subtract 4 from both sides
The area of the design is:
So, we have:
Plot the graph of
From the graph (see attachment), the maximum is at:
Substitute in
Divide both sides by 20
Hence, the dimension that maximizes the design (<em>excluding the margin</em>) is 20 inches by 20 inches
