Answer:
Step-by-step explanation:
hello : note 297 no 279
297 =3×99
99 = 3 ×33
33=3×11
this the geometric sequence. ( comon : 3)
the nth term is : An = A1 × r^n when : r = 3 and A1 =11
if n = 19 A19 = 11×3^19

Answer:
Step-by-step explanation:
Arc length of a circle is given by,
Arc length =
Here, θ = Central angle subtended by the arc
r = Radius of the circle
From the given picture,
θ = 45°
r = 1 unit
Therefore, arc length =
=
=
=
Arc length = units
= units
Angle θ has a measure =
= radians
