Question

the area of circle having diameter 28 cm is​

Answer 1

Answer:

616 cm²

Step-by-step explanation:

radius = diameter/2

= 28/2

= 14 cm

area of circle = πr²

= 22/7 × 14 × 14

= 616 cm²

Answer 2

Step-by-step explanation:

If diameter is 28 then Radius will be 14

$area \: of \: circle = \pi {r}^{2}$

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

$22 \times 14 \times 2$

$616 \: {cm}^{2}$
