The answer to the question is a
Volume of Sphere = (4/3)*(pi)*(r^3)
r = (D/2) = 6 m
=<span>(4/3)*(pi)*((6^3)
= 904.7786.. m^3
I hope this helps.</span>
|3+10|=|3|+|10|
|13|=|13|
13=13
The denominator tells you the total amount of pieces.
Answer:
b)0, yes
Step-by-step explanation:
Given:
Vectors (4,8) . (6,-3)
Finding inner product of vectors:
= 4x6 + 8x-3
=24-24
=0
Now to check the angle between them using formula a.b=|a|.|b|cosθ
|a|= 
=8.9
|b|=
=6.7
Putting values of a.b=0 and |a|=8.9, |b|=6.7 in a.b=|a|.|b|cosθ we get,
0= 8.9(6.7)cosθ
cosθ =0
θ=90 degrees
Hence the two vectors are perpendicular !
