Juliette [100K]

Answer:

863 cups

Step-by-step explanation:

step 1

Find the volume of the conical cup

The volume of the cone (cup) is equal to

$V=\frac{1}{3}\pi r^{2}h$

we have

$r=2/2=1\ in$ ----> the radius is half the diameter

$h=4\ in$

assume

$\pi =3.14$

substitute

$V=\frac{1}{3}(3.14)(1^{2})4=4.19\ in^3$

step 2

Find out how many cups of water must Carissa scoop out of the sink

Divide the volume of the sink by the volume of the cup

$\frac{3,617}{4.19}= 863\ cups$
