The value of a machine depreciates every year at the rate of 10% of its value the machine was purchases. for rs 40000 when new and it was sold for 29160 find the no. of years that the machine was used

40000·(1 - 0.1)^x = 29160 --> x = 3 years

i am unable to solve this problem

step-by-step explanation:

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
