Answer: first option.
Step-by-step explanation:
You know that the height of the smaller cylinder is 6 cm and the height of the larger cylinder is 18 cm, then you can find the volume ratio. This is:
Knowing that the volume of the larger cylinder is 40,635 cubic centimeters, you need to multiply it by the volume ratio to find the volume of the smaller cylinder.
Therefore:
Step-by-step explanation:
Since Ca(OH)2 is Basic, we need to find pOH:
pOH = - log [OH-]
pOH = - log(0.0001)
pOH = - ( - 4)
pOH = 4
Since, pH + pOH = 14
Therefore,
pH of 0.0001M sol. of Ca(OH)2 = 10
Meat =35/100
vegetables =15/100
sauce =5/100
bread =5/100
Answer:
h=4/3 r Base area =27(pi)/16 h^2
Step-by-step explanation:
The Volume of the following solids are
Cylinder: (pi)r^2 h
Sphere:4/3 (pi) r^3
Pyramid: 1/3(base area) h
Assuming that the Volume is the same in all three solids
(pi)r^2 h= 4/3 (pi) r^3
Simplify
h=4/3 r
(pi) r^2 h= 1/3(Base area)h
Simplify
(pi) r^2= 1/3 base area
substitute r=3/4 h
(pi) 9/16 h^2=1/3 base area
Base area =27(pi)/16 h^2
