Help ASAP! Find The Area Of A Circle With R =20.5

Step-by-step explanation:

Pi*r^2 = Area

20.5^2 * Pi = 1320.25

answer4 to the second power is 16

and 4 to the third power is 64,

graph #4 (last graph) depict the function   f(x)= -m(x-d)^1/5 i

step-by-step explanation:

we know that

m=slope

but in this function slope is -m that means slope is decreasing and it is decreasing by 1/5 points down the x-axis.

which is shown in graph four

a decreasing slope down x-axis by 1/5 points.

hence 4th graph is the right option for this.
