Acircle is circumscribed about a square. if the sides of the square are 3, what is the approximare circumference of the circle? round your answer to the tenths place.

a. 18.8
b. 13.3
c. 9.4
d. 28.3

B. 13.3

Step-by-step explanation:

First, find the diagonal of the square, as it is also the diameter of the circle:

Area of the circle is 2πr, which can be simplified as dπ:

1,8,15,22,29,36,43,50

step-by-step explanation:

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

the factor is 2

step-by-step explanation:

let f(x)=8(3^(x−2)+2)

to stretch a graph by 3, it would be 3f(x)

g(x) =3f(x)

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

x     −2     0     2     4     6

f(x) 1/64 1/16   1/4     1     4

1/64 * z * z = 1/16

i multiplies by z twice because it its 2 steps from -2 to 0

1/64 z^2 = 1/16

multiply by 64 to clear the fraction on the left side

1/4 * 64 z^2 =1/16 *64

z^2 = 4

take the square root of each side

sqrt(z^2) = ±sqrt(4)

z = ±2  

we are multiplying by 2 each time.
