there is a formula A = 2π r h + 2π r².

=> h = (A - 2π r²) / 2π r

=> h = ( 616 - 2π(7)^2) / 2π(7)

=> h = 7.0

Triangle UVW is formed by the three squares G, H, and I:

The phytagorean theorem states a^2 + b^2 = c^2 And so your answer is C. (UV)^2+(VW)^2=(UW)^2, because 81+144=225

Since they are squares, the length of one sides square is equal to the area. UV, VW, and UW are all sides on a square. If you square them, you get their area, and then if you add the areas it will prove the phytagorean theorem correct.
