A storage tank used to hold sand is leaking. The sand forms a conical pile whose height is twice the radius of the base. The radius of the pile increases at the rate of 2 inches per minute. Find the rate of change of volume when the radius is 7 inches. A. 196π in.^3/min

B. 28π in.^3/min

C. 224π in.^3/min

D. 98π in.^3/min

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?

step-by-step explanation:

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3

f(x) is   are being squared

g(x) is   increasing by 2

h(x) is adding .25 each time

k(x) is taking the square root

f(x) and k(x) are exponential functions
