Answer 5

@AngelicMelody check your answers again. Use the formula Shamil gave above, and instead of using π use 22/7 as they asked you to, it should look like this : \[Area = \frac{ r² * 22 }{ 7 }\] with r=d/2=14

Answer 6

22/7 x 14 = 44

Answer 7

You forgot the power 2 and the unit at the end. 22/7 x 14² = 616 cm²
Good luck in your studies !
