4.1 Total resistant(R) in an electrical circuit is calculated as follows: R = R₂ + R₂ + R, (series connection)
土 1+1+1
(parallel connection)
R;
If R= 40, R2 = 60 and R= 80 (n = ohm)

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
