Question

Daren used rice to fill a cylindrical glass measuring 6 inches high with a radius of 2.5 inches. He
pours this rice into a cardboard cylinder that is 3.5 inches high with a diameter of 8 inches. Will he have
enough rice to fill the cardboard cylinder? Explain (must show all work) Round to the nearest tenth if
necessary.


plz show work I'll give extra points​

Answer 1

Answer:

no

Step-by-step explanation:

1. Find the area of the glass cylinder

$V=\pi 2.5^26$

$V=\pi (6.25)6$

$V=19.625(6)$

$V=117.8$

2. Find the volume of the cardboard cylinder

(the radius is 4 because $r=\frac{1}{2} d$ )

$V=\pi 4^23.5$

$V=\pi (16)3.5$

$V=50.24(3.5)$

$V=175.8$

$117.8<175.8$

the volume of the cardboard cylinder is greater than the volume of the glass cylinder so no, he will not have enough rice to fill the cardboard cylinder .
