1.a fish is dropped into the edge of an eight foot deep large cylindrical tank.the fish is a bit confused and swims 8 yards straight and runs into the tank.it then turns exactly 90 degress and swims straight for 6 yards and runs into the tank again.What is the volume of the tank in cubic feet
2.if a cup is 5 inches tall and holds 12 ounces how much liquid will a similar cup that is 9 inches tall hold?
3.in the circle sketch two triangles that are similar using A,B,C,D,E as vertices.
a.If DE=8,AE=4,and EB=6,then what is EC?
b.Will triangle drawn like this inside a circle always be similar?Explain.

第一题,看俯视图,先游8 yards,再转九十度,6 yards 1yard=3foot
圆柱底面(2R)^2=8^2+6^2所以,底面半径为15foot
圆柱容积就是V=πR^2h=1800π
第二道题,5英寸高,承载12盎司,地面面积就认为是12/5
那么,九英寸高,就有12/5*9=108/5盎司.
第三题,就是几何计算,小偷懒一下,就是相交弦定理.参考摆到底下,
知道定理,可以轻松算得EC=3
而至于证明后面的三角形,下面的证明里也有.

1.圆柱的直径:直角对应的是直径,于是勾股定理,得出d=10yards=30feet
高:8yards。1码=3英尺(foot)
v=1/4πd^2×h=1/4×30*30×24=5400cubic feet
2.还是,圆柱体积。相同底面积体积与高成正比。
答案:21.6ounces
3.
相似,圆中同一条弦对应的圆周角是都相等的。不会用英语

相似之后自然可以得出EC=3
