Question

If the circumference of a circle is 10 its area will be _____.​

Answer 1

Answer:

• Area will be 7.94 cm²

Step-by-step explanation:

Given

• Circumference of circle = 10 cm

To find

• Area of circle

Solution

• 2πr = 10
• 2 × 22/7 × r = 10
• 44/7 × r = 10
• r = 1.59 cm

∴ Radius of circle = 1.59 cm

• Area of circle = πr²
• 22/7 × 1.59 × 1.59
• 22/7 × 2.5281
• 7.94

∴ Area of circle = 7.94 cm²
