8x^2 +13x -6 =(8x-3)(x+2)
The problem is modelled as right angle triangle, shown in the diagram below
The distance between the pilot and the house is labelled as

Using the trigonometry ratio of sine


Answer:
9
Step-by-step explanation:
Vcylinder-Vsphere=water
Vcylinder=hpir^2
Vsphere=(4/3)pir^3
given
cylinderradius=30 and h=100
Vcylinder=100pi30^2=100pi900=90000pi
let's leave it in terms of pi for more exactness
sphereradius=12
Vsphere=(4/3)pi12^3=2304pi
cylinder-sphere=90000pi-2304pi=87696pi
using pi=3.14
water=275365.44 cubic cm
last option is corrrect
