Would they deduct marks for not including anything under 0?

was it any value greater than 300?
Yep I got 26 hours and I said from 0 to -100 and 300 to 310 (I know now I should have just put 'greater than 300' :(

Quite sure you got the perimeter question wrong. I think you did 230/360*pi*13 but then you have to add two lots of 13 because that previous calculation only does the circular part of the perimeter.

230/360 x 2pie x 13 +13+13 = 78.19 (2dp)

15 cm is correct

Perimeter of a circle - arc length formula

(2*pi*13) - (130/360 * 2*pi*13)

= 52. 16
