Given that the radius of the circle is 6 cm.
The central angle is 120°
We need to determine the length of AB.
<u>Length of AB:</u>
The length of AB can be determined using the formula,

Substituting
and
in the above formula, we get;

Simplifying the values, we get;



Substituting π = 3.14, we have;


Thus, the arc length of AB is 12.56 cm
Width=w
Length=l
Perimeter=p
p=2w+2l
l=20+w
p=2w+20+w+20+w
p=4w+40
4w+40=160
4w=160-40=120
w=120:4=30
w=30
l=20+w
l=20+30=50
(xᵃ .yᵇ)ⁿ = xᵃⁿ . yᵇⁿ
(3.x².y³)³ = 3³.x⁶.y⁹) = 27.x⁶ .y⁹
