[quote=Chloeeeeee post_id=1997403 time=1601777234 user_id=188699]There was a circles question in the psle something about circles and finding the perimeter of the shaded part? Does anybody have an ans to this? Thanks

i remember b) to be 1156.2cm2

I thought it was 1156.5[/quote]

It is 1156.5

It is definitely not 91, cos they started with Star so the pattern must follow accordingly, and not like the tuition. So it is not 91

For the heart and star question, it is (89,90).

They asked “What are the possible numbers of hearts there can be”
Since the pattern is “Star, Heart Star, Star, Heart” The last stars can be “Star, Heart, Star, Star” or
“Star, Heart, Star, Star, Heart”. Therefore, when there is no last heart it would be 89 but with the last heart it would be 90. So the answer should be (89,90).
