Answer 2

Given :-

• Diameter of the circle = 28cm.

To Find :-

• Area of the circle

Solution :-

★ Diameter of Circle ★

⇛ Diameter = 2 × Radius

⇛ 28 = 2 × Radius

⇛ 28/2 = Radius

⇛ 14 = Radius

━━━━━━━━━━━━

★ Area of Circle ★

⇛ Area of Circle = πr²

⇛ Area of Circle = 22/7 × (14)²

⇛ Area of Circle = 22/7 × 14 × 14

⇛ Area of Circle = 22 × 2 × 14

⇛ Area of Circle = 616cm²
