Question

The formula for the area (A) of a circle is A = π • r2, where r is the radius of the circle. Ronisha wants to find the area of a sector of a circle that has a central angle of π6 radians. Enter the number that Ronisha should multiply by to find the area of the sector of the circle. Round your answer to the nearest hundredth.

Answer 1

Greetings from Brasil...

Here we will apply rule of 3...

This formula, A = πR², its for the whole circle, that is, 360° (2π)

We want the area of only a part, that is, a circular sector whose angle π/6

sector area

2π ----- πR²

π/6 ----- X

2πX = (π/6).πR²

2πX = π²R²/6

X = π²R²/12π

X = πR²/12

If Ronisha multiply the area by 1/12 she will get the area of sector with angle of π/6
