700,000 is the answer...i think
I think “c” is the correct answer. I am not sure
Answer:
163.3m²
Step-by-step explanation:
area = Pi(r²)
r = d / 2
r = 12
12² = 144
144 x 3.14 = 452.16
diameter of bigger circle = 24 + 4 (2 on each side)
28 / 2 = 14
14² = 196
196 x 3.14 = 615.44
sidewalk = bigger - smaller
sidewalk = 615.44 - 452.16
sidewalk = 163.3
The inverse function of
is
<h3>How to determine the inverse function?</h3>
The function is given as:

Rewrite as;

Swap the positions of x and y

Multiply through by -2

Square both sides
4x^2 = y + 3
Subtract 3 from both sides
y = 4x^2 - 3
Express as an inverse function

Hence, the inverse function of
is
