Answer:

y = 40 / sqrt(pi)

Step-by-step explanation:

The area is 400

We want to find the diameter

400 = pi r^2

Divide each side by pi

400/ pi = r^2

Take the square root of each side

sqrt(400/ pi) = sqrt(r^2)

20/ sqrt(pi) = r

The diameter is twice the radius

2 r = d

2 * 20/ sqrt(pi) = d

40 / sqrt(pi) =d

y is the diameter so

y = 40 / sqrt(pi)

ANSWER

C. x=7

EXPLANATION

The given exponential equation is

${3}^{x - 5} = 9$

We rewrite the right hand side as 3 raised to exponent 2.

${3}^{x - 5} = {3}^{2}$

Observe that the base of both sides of the equation are equal.

We now equate the exponents.

$x - 5 = 2$

Solve for x,

$x = 2 + 5$

$x = 7$

The correct choice is C.
