Sin Yee's answer to Emily's Primary 6 Maths Fractions Singapore question.
Hello, I think the formula for circumference of a circle is 2πr. So the answer to this might not be right, but the concept of it is there. My answer I got was 271.33cm
And I got a different answer 287.03.
Dixon, you probably forgot about the small semicircle in the middle, which leads to your answer 271.
