A cylindrical frame consisting of three circles and four vertical supports is built from 6m of wire, as shown. The frame is then covered with paper to form a closed cylinder.(adsbygoogle = window.adsbygoogle || []).push({});

1. Determine an expression for the radius r in terms of the height h.

2. determine the restriction on the height if the radious of the cylendar must be atleast 10.

I got the first one;

1.r=3-2h/3pi

But I did not get the second one

2.

10 > 3- 2h/3pi

3pi(10)> 3- 2h

30pi-3 > -2h

(30pi - 3)/-2 < h

Can someone help me? Thanks
