http://https://imgur.com/gallery/108AXA cylinder of height h cm and radius r is enclosed on a cone of height 40cm and radius 12cm. Explain why ABC is similar to ADE? By using Ratios of corresponding sides, show that h=40-10/3r.

The question is Ex 12 G Q20 a, b from the Year 11 2U

Also can you do Q21 d from the same exercise
