Question

Find the area of circle of 270 degree sector with radius 3.5 cm.

Answer 1

Answer:

Step-by-step explanation:

Answer 2

The area of circle of 270 degree sector is 28.875 square cm

Solution:

The area of sector of circle is given as:

$Area\ of\ sector = \frac{ \theta }{ 360} \times \pi r^2$

Where, "r" is the radius

From given,

$r = 3.5\ cm\\\\\theta = 270^{\circ}$

Substituting the values we get,

$Area\ of\ sector = \frac{ 270 }{ 360} \times \frac{22}{7} \times 3.5^2\\\\Area\ of\ sector = \frac{ 270 }{ 360} \times \frac{22}{7} \times 3.5 \times 3.5\\\\Area\ of\ sector = 28.875\ cm^2$

Thus, area of circle of 270 degree sector is 28.875 square cm
