Answer 2

The perimeter is 7.33 cm and area of sector is 51.33 sq. cm.

Step-by-step explanation:

Since we have given that

radius = 14 cm

Central angle = 30 °

So, perimeter of sector of a circle would be

$\dfrac{\theta}{360^\circ}\times 2\pi r\\\\=\dfrac{30}{360}\times 2\times \dfrac{22}{7}\times 14\\\\=7.33\ cm$

Area of sector would be

$\dfrac{\theta}{360^\circ}\times \pi r^2\\\\=\dfrac{30}{360}\times \dfrac{22}{7}\times 14\times 14\\\\=51.33\ cm^2$

Hence, the perimeter is 7.33 cm and area of sector is 51.33 sq. cm.
