Question

Find the area of a sector of radius 7 cm and angle is 70°

Answer 1

Answer:

Step-by-step explanation:

Answer 2

$\huge{We \: know,}$

$\huge{Given,}$

$\huge{radius \: 7cm}$

$\huge{\theta = 70\degree}$

$\huge{Area \:of \:sector\: = \frac{\pi{ {r}^{2} \theta }}{360 \degree} }$

$\huge{=\frac{22 × 7 × 7 × 70}{7 × 360}}$

$\huge{=\frac{539}{18}}$

$\huge{=29.9{cm}^{2}}$
