The area of a sector is 1848 m2 and the central angle of the sector is 270°. Find the radius of the circle. (Take π = 22/7)
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 28 m.
We know that,
Area of sector = θ/360 × πr2
Now, according to the question,
⇒ 1848 = 270/360 × 22/7 × r2
⇒ r2 = (1848 × 360 × 7)/(270 × 22)
⇒ r2 = 784
⇒ r = 28 m
