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.

The width of a rectangle is 38 centimeters. the perimeter is at least 692 centimeters. write an inequality that represents all p

abruzzese [7]

Width of the reactangle = 38 cm

Minimum perimeter = 692 cm

Let the length of the rectangle be x cm

We know that,

Perimeter of rectangle = 2 * (length + width)

Since the perimeter should be atleast 692 cm. Therefore,

2 * (x + 38) > 692

2x + 76 > 692

2x > 692 - 76

2x > 616

x > $\frac{616}{2}$

x > 308

Hence, the length of the rectangle should be more that 308 cms.
