Answer:
y ≈ 4.3 cm
Step-by-step explanation:
Given 2 secants from an external point to the circle.
The the product of the external part and the entire part of one secant is equal to the product of the external part and the entire part of the other secant, that is
3(3 + y) = 2(2 + 6 + 3) = 2(11) = 22, that is
9 + 3y = 22 ( subtract 9 from both parts )
3y = 13 ( divide both sides by 3 )
y ≈ 4. 3 cm ( to the nearest tenth )

c)
Step-by-step explanation:
A tank has the format of a cylinder.
The volume of the cylinder is given by:
In which r is the radius and h is the heigth.
The problem states that the diameter is measured to be 15.00 ft. The radius is half the diameter. So, for this tank
ft
The height of the tank is 22 ft, so 
.
a) Volume of the tank in 
:
b) Volume of the tank in 
:
We must convert both the radius and the height to m.
Each feet has 0.30 m, so:
Radius:
1 feet - 0.30m
7.5 feet - r m
Height
1 feet - 0.30m
22f - h m
The volume is:
c) Volume of the tank in 
:
Each m has 100 cm.
So 
The volume is:
