on positive x-axis we will plot x=2 and on negative y-axis we plot y=-4

Step-by-step explanation:

We need to plot the point(2,-4) on the graph

For plotting on the graph we need x and y values

We are given ordered pair (2,-4) so, x = 2 and y=-4

So, on positive x-axis we will plot x=2 and on negative y-axis we plot y=-4

The graph is shown in figure attached

R(t) = 4t
A(r) = π(r^2)

a) A(t) = A[r(t)] = π[r(t)]^2 = π[4t]^2 = 16π(t^2)

b) t = 4,

A(4) = 16*3.14*(16)^2 = 12,861.44
