Answer 2

★ Given :-

• Diameter is 60 cm.
• Radius is 60 / 2 = 30 cm.

★ To Find :-

• Circumference and Area of a circle ?

★ Solution :-

◆ We know that,

⇒ Circumference of a circle = 2πr

Now substitute the values :-

↦ Circumference of a circle = 2 × 22 / 7 × 30

↦ Circumference of a circle = 44 / 7 × 30

↦ Circumference of a circle = 6.28 × 30

↦ Circumference of a circle = 188.4 cm

◆ We also know that,

⇒ Area of a circle = πr²

Now substitute the values :-

↦ Area of a circle = 22 / 7 × 30 × 30

↦ Area of a circle = 22 / 7 × 900

↦ Area of a circle = 2828.57 cm².

■ Circumference of a circle is 188.4 cm and Area of a circle is 2828.57 cm².
