How many cubic centimeters of water can this paper cone cup hold?
blagie [28]

48π cm^3

Step-by-step explanation:

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

V=\frac{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=\frac{1}{3}*(\pi *4*4*9)

V=\frac{1}{3}*(144\pi )

V = 48π

The paper cone can hold <u><em>48π cubic centimeters</em></u> of water.

How do I solve this and what kind of formula is it?
soldier1979 [14.2K]

Answer:

160

Step-by-step explanation:

The measure of an arc is always twice the degree of the corresponding angle inside the circle. For example, the measure of arc DC is just double the measure of angle DOC; angle DOC is 44 degrees, so arc DC must be 88 degrees.

Angle COB is 80 degrees, so arc CB is 160 degrees.
