Water leaks from a crack in a vase at a rate of 0.5 cubic inch per minute. How long does it take for 20% of the water to leak from a full vase?

the cone is 4.8 inch in diameter. and 10 inches in height. the formula is (1/3) x 3.14 x radius squared x height.

Find total volume to find what amount is 20%

hack, is put the 20% in alreadyy to find 20% volume

20%=1/5

so

vcone=1/3 (hpir^2)

times thath by 1/5

vcone=1/15 (hpir^2)

d/2=r

given

4.8=d

4.8/2=d/2=r=2.4

10=h

V=1/15 (10pi2.4^2)

V=1/15 (10pi5.76)

V=1/15 (57.6pi)

V=3.84pi

V=12.0637 cubic inches=20% of vase

0.5 cubc inches per min

0.5 times t=12.0637

divide both sides by 0.5

t=24.1237

about 24 minutes
