Question

Find the area of a circle whose:
(1) Radius=7 cm​

Answer 1

$area \: of \: circle = \pi {r}^{2 } \\ = \frac{22}{7} \times {7}^{2} \\ = 22 \times 7 \\ = 154 \: {cm}^{2}$

Answer 2

Answer:

$\huge {\underline {\underline {\mathbf {\color{plum}{ANSWER:-}}}}}$

${\underline {\underline {\bf{Given \: radius = 7 cm }}}}$

$\rm{We \: know \: that \: area \: of \: circle = π {r}^{2} }$

$\small \rm{A = ( \frac{22}{7} ) × {7}^{2} }$

$\small \rm{A = 22 × 7}$

$\rm{A = 154 {cm}^{2} }$
