10 books because the ratio is 2:5 and you have 4:x so x=10 ((:
Volume of cone= 1/3 πr²*h
15²=10²+h²
h²=15²-10²=125
h=√125
Volume of cone= 1/3 *π*100*√125=π/3*(100*5√5)=500π√5/3
Volume of sphere=4/3*π*r³=4/3*π*1000=4000π/3
Volume of half sphere=(4000π/3)/2=2000π/3
All Volume=500π√5/3+2000π/3
Answer:
about 11.50
Step-by-step explanation:
6 / 5.70 = 1.05
1.05 x 11
hope this helps
3.45. All you have to do is divide 10.35 by 3.
