The circumference of the larger circle is approximately 22 meters and the circumference of the smaller circle is approximately 11 meters. Use a proportion to find the approximate diameter of the smaller circle. If necessary, round your estimate to the nearest tenth.

approximately 3.5 meters.

Step-by-step explanation:

Given: Circumference of the smaller circle is approximately 11 meters.

Circumference of a circle = , where d= diameter.

Ratio of circumference to diameter =

As per given,

Hence, the diameter of the smaller circle is approximately 3.5 meters.

answer:   rotate 270° clockwise about (7, 1) and reflect across the line x = 7

step-by-step explanation:

because i took test

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
