The semi-vertical angle of a cone is

45^{\circ}

. If the height of the cone is 20.025, then its approximate lateral surface area, is

View answer and explanation

Correct option: A

401 \sqrt{2} \pi

Option A (

401 \sqrt{{2}} \pi

) is correct because it represents the approximate lateral surface area of the cone, calculated using differentials.
