Answer:
I believe that those triangles are not similar
Step-by-step explanation:
5 is 1.666 of 3
20/3=6.667
1.666 does not equal 6.667
if I did that correctly, they are not similar
Hope this helps!
Ratio of Nickel to Zinc:
( 2/7 ) = ( Nickel /4.9)
Nickel = 1.4 lbs.
Ratio of Copper to Zinc:
( 9/7 ) = ( Copper /4.9)
Copper = 6.3 lbs.
Alloy = Zinc + Nickel +
Copper
Alloy = 4.9 lbs. + 1.4 lbs.
+ 6.3 lbs.
Alloy = 12.6 lbs.

Step-by-step explanation:
Solution:
Here,
Volume of the tank=539 litres
=539×1000cm^3=539000cm^3
Height=1.4×100cm=140cm
Let the radius of the base be r cm
Then,
22/7×r^2×140=539000
or,r^2=539000×7/22×140
or,r^2=1225
or,r=35 cm
So,
Area of base=pie r^2
=22/7×35^2
=3850 cm^2
