Find the area of this sector.
First write down your formula down for finding the area of the sector:
A = x/360 × π × r²
Now the radius of the circle is 7cm and the angle of the sector is 67⁰.
So substitute these numbers into the formula above.
A= 67/360 × π × 7²
You can type this all in one go on your calculator if you use the fraction button.
A= 28.6 cm² to 3 significant figures.
