Question

find the area of circle of diameter 30 cm. (use π=3.14)​

Answer 1

$given \\ diameter(d) = 30cm \\ \\ therefore \\ radius(r) = \frac{d}{2} \\ = \frac{30}{2} \\ = 15cm \\ again \: therefore \: \\ area \: of \: circle \: = \pi {r}^{2} \\ = 3.14 \times {15}^{2} \\ = 3.14 \times 225 \\ = 706.5 {cm}^{2}$

Refer from above

Answer 2

$\huge\colorbox{pink}{Answer}$

given

Diameter = 30cm.

∴

Radius (r) = d/2

=30/2

=15

Area of circle = πr²

= 3.14 * (15)²

=3.14 * 225

=706.5m²
