Answer:
P = 0.09r²
Step-by-step explanation:
Price, p is proportional to the square of its radius, r
P = k*r²
a mirror with radius 20cm has a price of £36
P = k * r²
36 = k * 20²
36 = k * 400
36 = 400k
k = 36/400
k = 0.09
Substitute the value of k into the equation:
P = k * r²
P = 0.09 * r²
P = 0.09r²
There are 8 people, but only 2 pies. So to figure out how much each person gets when divided, which is a keyword, equally. So to put it in fraction form it would be 2/8. If you simplify it you get 1/4. In decimal form, 2/8 and 1/4 both equal 0.25. Hope this helps you to understand it a bit more!
