1.	Area of a circle is 154 m2. Find out the perimeter of circle?1. 14 cm2. 44 m23. 44 m4. 7 m
Answer» Correct Answer - Option 3 : 44 m Given: Area of circle = 154 m² Formula used: Area of circle = πr² Perimeter of circle = 2πr Calculation: πr² = 154 m² ⇒ (22/7) × r² = 154 m² ⇒ r² = 7 × 7 ⇒ r = 7 m Perimeter of circle = 2 × (22/7) × 7 m ⇒ 44 m ∴ The perimeter of circle is 44 m

Area of a circle is 154 m2. Find out the perimeter of circle?1. 14 cm2. 44 m23. 44 m4. 7 m

Answer» Correct Answer - Option 3 : 44 m

Given:

Area of circle = 154 m²

Formula used:

Area of circle = πr²

Perimeter of circle = 2πr

Calculation:

πr² = 154 m²

⇒ (22/7) × r² = 154 m²

⇒ r² = 7 × 7

⇒ r = 7 m

Perimeter of circle = 2 × (22/7) × 7 m

⇒ 44 m

∴ The perimeter of circle is 44 m
