Determine the perimeter of a sector circular aob whose radius has a length of 4m its central angle is 0.5 rad

Which of the following is the rational exponent expression of 6 root f

Hurry and answer this! circle x with a radius of 6 units and circle y with a radius of 2 units are shown which steps would prove the circles similar? translate the circles so they share a common center point, and dilate circle y by a scale factor of 4. translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle y by a scale factor of 4. translate the circles so they share a common center point, and dilate circle y by a scale factor of 3. translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle y by a scale factor of 3

Which of the following is most likely the next step in the series? a3z, b6y, c9x, d12w, е15v, f18u
