If an error of

1^{\circ}

is made in measuring the angle of a sector of radius

30 \mathrm{~cm}

, then the approximate error in its area, is

View answer and explanation

Correct option: C

2.5 \pi \mathrm{cm}^2

Option C (

2.5 \pi \mathrm{{cm}}^2

) is correct because it is the approximate error in the area of the sector calculated using differentials.
