Which of the following statements is INCORRECT about the circle?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. The length of an arc = central angle made by the arc/360 × πr2.
Option 1:
The area of a sector = (arc length × R)
Correct statement
Option 2:
The length of an arc = central angle made by the arc/360 × πr2
Wrong statement
The length of an arc = central angle made by the arc/360 × 2πr [correct statement]
Thus, Option 2 is incorrect
