A cosmetic container in the shape of a cylinder has a diameter of 7 centimeters and a height of 3 centimeters. Which is closest to the volume of the container?

the closest to the volume of the container is 115.4 cm³

Step-by-step explanation:

To find the volume of the container, we simply use the formula for calculating volume of a cylinder;

V = π r ² h

Where  π is a constant

r is the radius and h stands for height.

From the question given, diameter = 7 cm, but radius if half of the diameter, which implies;  r = d/2 = 7/2 = 3.5 cm

h = 3 cm          π ≈3.14

We can now proceed to insert our values into the formula;

V = π r ² h

     ≈ 3.14×3.5² × 3

     ≈ 3.14 × 12.25 × 3

       ≈115.395

         ≈115.4 cm³

Therefore the closest to the volume of the container is 115.4 cm³

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
