Step-by-step explanation:
Answer:
13 foot rounded to the nearest foot
Step-by-step explanation:
the ratio is
nose to head: 2:9
Rushmore mountain Roosevelt :
nose to head : x/60
2/9=x/60
120=9x
x=120/9= 13 1/3 or 13.33
x=13 foot rounded to the nearest foot
Vcylinder=hpir^2
Vsphere=(4/3)pir^3
Vcone=(1/3)hpir^2
Vcylinder=15*pi*5^2=375pi in^3
Vsphere=(4/3)*pi*6^3=288pi in^3
Vcone=(1/3)*15*pi*8^2=320pi in^3
greatest is Vcylinder at 375pi in^3
answer is A (cylinder)
