Answer 1

48π cm^3

Explanation:

The formula for the volume of a cone is...

`V=(1)/(3)\pi r^2h`

We can plug everything we know from the photo into the equation, but note that the picture gives us the diameter, which is 8, instead of the radius. The radius is half of the diameter, so the radius will be 4. Also we will be leaving pi as it is, instead of changing it to 3.14.

`V=(1)/(3)*(\pi *4*4*9)`

`V=(1)/(3)*(144\pi )`

V = 48π

The paper cone can hold 48π cubic centimeters of water.

Answer 2

Explanation:

d = 8 cm

r =8/2 = 4 cm

h = 9cm

Volume of cone = (1/3)πr²h

`=(1)/(3)\pi *4*4*9\\`

= 4*4*3*π

= 48π cubic centimeteres
