If a+b+c = 0 then a3 + b3 + c3 is equal to
a. abc
b.0
c.3abc
d.9abc​

a.

=abc

=0*0*0

=0

b.

=0

c.

=3*abc

=3*0

=0

d.

=9*abc

=9*0

=0

B. 0

Step-by-step explanation:

Given :-

a+b+c =0

Now ,

a3+b3+c3

= 0×3+0×3+0×3

= 0

answer: your answer is a

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
