In Exercises 1-6, use the Regular Polygon Area formula to find the unknown length to the nearest unit or square unit. Recall that the symbol & is used for measurements or calculations that are approximations. Show all work! WTFSS 1. 4- 3. Pul # = 24 cm * = 107.5 cm : 30.6 em 24.9 cm " 19.$87.5 cm- 4 4940.5 cm" 4. Regular pentagon: a = 3 cm and = $ 4.4 cm. A N 5. Regular n-gon: a = 9.6 cm and A $ 302.4 cm , P R 6. Find the approximate length of each side of a regular n-gon if a = 80 feet, n = 20, and A 20,000 square feet. In Exercises 7 - 12, find the surface area of each prism or cylinder. All given measurements are in centimeters. All quadrilaterals are rectangles, unless otherwise labeled. WTFSS. 7. 8. 9. 1710. The base is a trapezoid. 11. 12.
