Question

find the area of circle . Radius =7m​

Answer 1

Explanation:

area = pi × r^2

= 22/7 × 7 × 7

= 154 m^2

Answer 2

Area of a circle = π$r^{2}$

When $r= 7$, we need to substitute $7$ in the place of $r$ in the equation π$r^{2}$

$=3.14 \times 7^{2}$

$=3.14 \times 49$

$=153.86m^{2}$

Therefore, the area of a circle with the radius of $7m$ is $153.86m^{2}$
