your calculations for volume (pi x r^2 × h) and surface area (2 × pi × r (h+r)) are correct. However your ratio are incorrect. From the formulas the ratio of surface area to volume would be r×h:2(h+r)

Given:
Customers can pick their own blueberries at Blueberry Hill. They pay $5 to enter the patch and $4 per pound for the blueberries they pick.
Required:
We have to write an equation to model the given expression.
Explanation:
Let the total cost be y,
And x denotes the amount in pounds of blueberries.
Since, Given to enter the patch customers pay $5 (fixed)
and Given the customers pay $4 per pound for the blueberries they pick so for x pounds of blueberries cost 4x
Thus, total cost y = 4x + 5
Thus, Option (a) is correct.
