It’s 15 for #16 and then for #18 it would be 55 then for 20 it would be 6
1.) A = πr^2
Rate of change (dA/dr) = 2πr.
When r = 3, dA/dr = 2(3)π = 6π ft^2/ft
2.) V = πr^2h
Rate of change of volume given constant r is dV/dt = πr^2dh/dt = π(6)^2(3) = 108π cm^3/min
Answer:
wpild be about 3 to 1 juice to pop
Answer: 36
Explanation:
h(x) = 4x^2
Find h(3):
Simply plug x = 3 in the function:
h(3) = 4(3)^2
h(3) = 4(9)
h(3) = 36
