Radius of cone is decreasing at the rate of 
inches
What is rate of change?
Suppose there is a function and there are two quantities. If one quantity of a function changes, the rate at which other quantity of the function changes is called rate of change of a function.
Here rate of change of radius of cone has been calculated
Radius of cone = 18 inches
Height of cone = 11 inches
Volume of cone (V) =

Step-by-step explanation:
(2(x+y)÷(x+y)(x-y) )×(x+y÷(x^2+2×x×2y+2y^2)
2÷x^2+2y^2
------------------------------------------------------
Change the denominators to be the same
------------------------------------------------------
5/ 8 = 5/8
7/4 = 14/8
Since the denominators are the same, the larger the numerator, the larger the fraction. Therefore 14/8 (7/4) is greater than 5/8.
14/8 > 5/8
7/4 > 5/8
---------------------------------------------------------------------------------
Answer: The grasshopper that is 7/4 unit long is longer

The answer i am guessing is going to be c and d.
