There is this one paper that has been bugging me for a while now. I don't exactly understand what I am getting wrong on some certain things. The ones I need help with are 10-13. So not much... Please... I really need help with this. It would be so appreciated if you could help me!

10. C= (pi) (2) (radius)
32 divide by (2)(pi) = radius
therefore radius is 10.18
Area = (pi) (radius ^ 2)
325.6 yards^2
11. trick bike radius = 20/2 = 10inch
A = 10^2 (pi)
314.16
mountain bike radius = 26/2 = 13inch
A = 13^2 (pi)
530.93
racing bike radius = 27/2 = 13.5
A = 572.55
12. A of triangle = (1/2) (b) (h)
(1/2) (8) (2.3)
= 9.2 ft^2
A of octagon = (1/2) (b) (h)
(1/2) (18.1) (15)
= 135.75
there are 8 triangles thus 135.75 x 8
= 1086 mm^2
Do 13 urself now i m tired and i have my own work to do :)
