You mean 28 divided by 7 bc thats 4 and for the other thing that is not the correct thing and it could never be true soooo.
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
Answer:
~150.79645 cm
Step-by-step explanation:
A=2πrh+2πr2=2·π·3·5+2·π·32≈150.79645
That would be point A. Point A is inside the outer bigger circle AND the smaller inner circle
Hope this helped!
