Alarge cylindrical cereal bowl has a 1.8-m diameter and a height of 0.7 m. calculate the volume of cereal that could be put into this bowl. the volume of the large cereal bowl is?

Answer

Find out the what is the volume of the large cereal bowl.

To prove

Formula

Where r is the radius and h is the height of cylinder .

As given

A large cylindrical cereal bowl has a 1.8m diameter and a height of 0.7 m.

As

Radius = 0.9 m

Height = 0.7 m

Put in the formula

Volume of a cylinder = 1.78m³.

Therefore the volume of the large cereal bowl is 1.78m³ (Approx) .

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
