Andre has a cylindrical pitcher to use to fill his aquarium with water. The pitcher is 20 cm high and has a diameter of 6 cm. His aquarium holds about 4,000 cubic cm of water. Approximately, how many times will Andre have to fill his pitcher in order to almost fill the aquarium?

Andre have to fill his pitcher approximately 7 times in order to almost fill the aquarium.

Step-by-step explanation:

We are given the following in the question:

Dimension of pitcher:

Height,h = 20 cm

Diameter, d  = 6 cm

Radius, r =

Volume of pitcher = Volume of cylinder =

Volume of aquarium = 4,000 cubic cm

Number of times pitcher is refilled =

Thus, Andre have to fill his pitcher approximately 7 times in order to almost fill the aquarium.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
