Question

A circle has a diameter of 14 cm.calculate it's area.
Area= πr²

$\frac{22}{7} \times 14 \times 14$
$22 \times 14 \times 2$
$612$



​

Answer 1

area of the circle=pi r square

=22/7×7×7

154

Answer 2

diameter of circle = 14 cm

radius of circle = d/2 = 14/2 = 7 cm

area of circle = πr²

= 22 × 7 × 7

7

= 22×7

= 154cm²

so the area of circle is

154 cm²

hope it helps.
