There are no numbers that answer should be symbolic. There should be 2 coordinates that are symbolic.

For the shape below, calculate the second moment of area (moment of intertia) with respect to the x-axis. Express your answer as "ans" x 10 to the power -3 and only put the "ans" part of your answer in the box provided. Make sure your answer is in m to the fourth. Use two decimal places. 25 mm 25 mm 100 mm 25 mm 50 mm 100 mm -751 75 mm 75 mm 50 mm 25 mm

Problem 1. Three circles are tangent externally. The distance between their centers are 60 m, 73 m, and 85 m. Find the radius of the largest circle. Problem 2. Six congruent circles are arranged in a way that each circle is tangent to at least two other circles. If the radius of each circle is 2 m, find the perimeter of the polygon formed by connecting the centers of each circle. Problem 3 If y varies inversely as z and y = 23 when z = 45,000, find y when z = 54,000.
