Given :

⬤ a) Radius = 21 mm

⬤ b) Diamater = 14 cm

⬤ c) Radius = 35 mm

To Find :

⬤ Area of Circle.

Formula Used :

\bf[\:{Area \: of \: Circle = \pi{r}^{2}\:]}

Solution :

A) Radius = 21 mm

According to the Formula :-

πr²

22/7 × 21 × 21

22 × 21 × 3

1386

Therefore , Area of Circle is 1386 mm².

═════════════════════════

B) Diameter = 14 cm

  • Radius = 7 cm

According to the Formula :-

πr²

22/7 × 7 × 7

22 × 7

154

Therefore , Area of Circle is 154 mcm².

═════════════════════════

A) Radius = 35 mm

According to the Formula :-

πr²

22/7 × 35 × 35

22 × 35 × 5

3850

Therefore , Area of Circle is 3850 mm².
