according to the formula
length of arc= ∅/360 * 2πr
radius=3.5 ∅=60°
therefore, l= 60/360 * 2*22/7*3.5
l= 1/6*7* 22/7
l= 22/6
l=11/3cm

To find the length of the arc PXQ, we need to first find the length of the circumference of the circle and then use the given angle to find the length of the arc.
The circumference of a circle with radius 3.5cm is given by the formula:
C = 2πr
where r is the radius of the circle and π is the constant pi.
Substituting the given values, we get:
C = 2 x (22/7) x 3.5
C = 22 cm (approx)
Therefore, the circumference of the circle is approximately 22 cm.
Now, we can use the given angle to find the length of the arc PXQ. The angle POQ is 60 degrees, which is one-sixth of the total angle around the center of the circle (360 degrees). Therefore, the length of the arc PXQ is one-sixth of the circumference of the circle:
Length of arc PXQ = (1/6) x C
= (1/6) x 22
= 3.67 cm (approx)
Therefore, the length of the arc PXQ is approximately 3.67 cm. that is also 11/3 cm
