### AC Lim's answer to Rossa's Secondary 3 E Maths Malaysia question.

Still dont understand.. How can get 270/360

POR is right angle = 90

PQR = 360-90 = 270

PQR = 360-90 = 270

Oh, but 270/360 equal to 3/4 not 3/2?

3/4 x 2 x (22/7) x 7

I simplified 3/4 x 2 = 3/2

So left 3/2 x 22/7 x 7

I simplified 3/4 x 2 = 3/2

So left 3/2 x 22/7 x 7
