Area of circle = pi x r^2
= 22/7 x 40^2
= 5028.57
= 5030cm^2 (3 SF)
30x^7
Multiply the coefficients (6•5) to get 30, then add the exponents (4+3) to get 7
Hope this helps!

Step-by-step explanation:
C
The new perimeter of the rectangle if the dimensions are quadrupled would be 72 inches.
<h3>What are the side lengths of the first triangle?</h3>
The perimeter is always obtained by adding all the sides. This means the possible side lengths of the original rectangle are:
- 5 inches + 5 inches + 4 inches + 4 inches
<h3>What are the side lengths of the new triangle?</h3>
5 inches x 4 = 20 inches
4 iches x 4 = 16 inches
<h3>What is the new perimeter?</h3>
20 + 20 + 16 +16= =72 inches

Replace the range for f(x)
So...
0=4-2x
x=2
4=4-2x
x=0
8=4-2x
x=-2
