volume for a sphere (ball) is 4/3 x PI x r^3
r = 6.3, r^3 = 6.3^3 = 250.047
volume = 4/3 x 3.14 x 250.047 = 1046.863
rounded to nearest hundredth = 1046.86 cubic inches
Answer:
SAS
Step-by-step explanation:
AC is a shared side.
AB and DC are the same length. (Given)
BAC and ACD are same (Given)
To get the distance of the balloon from the the bottom to the ground we apply the following trigonometric formula:
sin θ=opposite/hypotenuse
θ=35°
opposite=height,h
hypotenuse=75ft
Thus plugging our values in the formula we obtain:
sin 35=h/75
solving for h we get
h=75sin 35
h=43.02~43 ft
What you do is you rearrange and simplify both equations to have them in terms of y, and then graph them. If it asked for a solution, their point of intersection would be the solution.
