Question

An arc subtends an angle 15 degrees at the centre of the circle. If the radius is 4 centimetres, find the area of the sector?

Answer 1

area of whole circle = 16π cm^2
15° = 1/24 of a rotation, so the are of the sector is
(1/24)(16π) = 2π/3 cm^2

Answer 2

Thanks Reiny. it was simpl right?
