I'm going to suppose that this is asking for the volume.
The formula to find volume for a cylinder is<span> V= pi r 2(squared) h
</span><span><span />The radius is 10cm and the height is 14cm
Then plug the numbers in
So you should get V=3.14 x 10(squared) x 14
The once you multiply all that you should get 4396 cm(cubed)

Mariana [72]

Answer:

Cost of tshirt = £7.29

Cost of what = £0.86

Step-by-step explanation:

2t +3h = 12; 10t + 15h = 60

5t + 4h =33; 10t + 8h = 66

15h -8h = -6

7h = -6; h = -6/7; h = 0.86

2t +3(-6/7) =12

14t -18 = 84

14t = 102; t = 102/ 14; t=7.29
