![\hookrightarrow \sf (3.14)(8)^2 +(3.14)(8)(18)](https://tex.z-dn.net/?f=%5Chookrightarrow%20%5Csf%20%283.14%29%288%29%5E2%20%2B%283.14%29%288%29%2818%29)
![\hookrightarrow \sf 653.1 cm^2](https://tex.z-dn.net/?f=%5Chookrightarrow%20%5Csf%20653.1%20cm%5E2)
R parallel to s
because <4 =<5 alternate
2/1 or 2
either or is correct, just depends on how your teacher prefers your answers to be
Answer:
