A paint can holds 2.5 litres =2,500 cm3

The can is 15cm tall.

What is the radius of the can?

Thank you

The radius of the can is 7.28 cm .

Step-by-step explanation:

By our general knowledge, a "can" is a cylinder. It is given that the volume of can is 2500 cm³ and the height is 15 cm tall so we have to use the formula of volume of cylinder to find the radius :

Let r be radius, v be volume and h be height,

Let v = 2500 cm³,

Let h = 15 cm,

7.3cm

Step-by-step explanation:

Volume=2500

π=3.14

volume of cylinder=πxr^2xh

2500=3.14xr^2x15

2500=47.1xr^2

r^2=2500/47.1

r^2=53.8

r=√(53.8)

r=7.3

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

where are the images of the functions i can only see the question you typed.
