Find the volume of a coffee can with r=7.5 cm, h= 16.8 cm, to the nearest cubic centimeter.
andriy [413]

Answer:

V = 2968.8 cm³ or 2969 cm³

Step-by-step explanation:

Given the radius, r = 7.5 cm, of a cylindrical coffee can whose height, h = 16.8 cm:

We can find the volume of a cylinder by using the following formula:

V = πr²h

Substitute the given values into the formula:

r = 7.5 cm

h = 16.8 cm

V = πr²h

V = π(7.5)²(16.8)

V = π × 56.25 × 16.8

V = 2968.8 cm³ or 2969 cm³

Therefore, the volume of a coffee can is 2969 cm³.

Which is the constant of proportionality for the data in the table?
Lisa [10]

Answer:

C) 6

Step-by-step explanation:

From the given data we can find the constant of proportionality by dividing The number of people by number of cars.

Constant of proportionality = \frac{\textrm{Number of people}}{\textrm{Number of cars}}

Taking any point from the table will give the same constant of proportionality as they are proportional quantities.

Constant of proportionality = \frac{18}{3}=\frac{30}{5}=\frac{36}{6}=\frac{48}{8}=6

This can be written as 6 people per car.

For 10 cars, number of people will be =10\times 6=60 people.
