A paper cup in the shape of an inverted cone is 8 inches tall and has a radius of 1.5 inches. How much water can the cup hold?

Use 3.14 for Pi. Round the answer to the nearest tenth.

The cup can hold 18.84 cube in water.

Step-by-step explanation:

Given,

The height (h) of the inverted cone = 8 inches

The radius of the base (r) = 1.5 inches

To find the amount of water the cup can hold

That is to find the volume of the cup.

Formula

The volume of a cone with h as height and r as base is = πr²h

Now, putting the values of r and h and π =3.14 we get,

Volume =  ×3.14×1.5²×8 cube in = 18.84 cube in

Hence,

The cup can hold 18.84 cube in water.

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
