The area of a circle is 121π ft². What is the circumference, in feet?

· Area = pi*r^2. 121 = pi*r^2. Solve for r. Circumference = 2*pi*r. plug r into that equation and solve for Circumference

Use the given functions to set up and simplify f e e t . 121 π f t 2 = f e e t = f e 2 t

step-by-step explanation:

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
