A conical paper cup has dimensions as shown in the diagram. How much water can the cup hold when full? A. 30π cm3 B. 35π cm3 C. 40π cm3 D. 45π cm3

mhanifa:

What is the dimensions, can you attach a picture?

mhanifa:

We need to know the radius and height of the cone to calculate its volume

mhanifa:

Use formula: \[V = \frac{ 1 }{ 3}\pi r^2h\]

shyshy101:

6 and 10

mhanifa:

Which is the radius?

mhanifa:

Can you attach its diagram?

shyshy101:

1 attachment
mhanifa:

Ok, we have diameter 6 cm, the radius is half of this: d = 6 cm r = d/2 = 6/2 = 3 cm

mhanifa:

h = 10 cm

mhanifa:

Can you calculate using the formula?

shyshy101:

idk how

mhanifa:

Substitute r and h into formula above

mhanifa:

\[V = \frac{ 1 }{ 3 }\pi (3^2)(10) = \frac{ 1 }{ 3 }\pi(9)(10) = 30\pi \]

mhanifa:

Its option A
