Volume of cone=1/3 times height times pir^2
v=15
r=3
15=1/3 hpi3^2
15=1/3hpi9
15=9/3hpi
15=3hpi
divide 3
5=hpi
h=5/pi
pi=aprox 3.14
5/3.14=1.59
1.59 ft
4 = amount
<span>8 = base </span>
<span>amount / base = percent </span>
<span>4 / 8 = 0.50 </span>
<span>multiply 100 times the decimal and attact he % symbol </span>
<span>100 x 0.5 = 50 % </span>
<span>4 is 50% of 8 </span>
-15-22+x
-36+x
I think that's the answer (at least that's what I got) hope this helps★
