Question

The circumference of a circle is 440m find it's area

Answer 1

Answer:Using the formulas

A=πr2

C=2πr

Solving forA

A=C2

4π=4402

4·π≈15406.19849m²

Step-by-step explanation:

Answer 2

Answer:

area of circle is 15400 m²

Step-by-step explanation:

given, circumference of circle is 440

circumference of circle = 2πr

440 = 2 × 22/7 × r

440 = 44/7 × r

(7 × 440)/44 = r

7 × 10 = r

r = 70m

now, area of circle = πr²

= 22/7 × (70 × 70)

= 22 × 10 × 70

= 22 × 700

= 15400 m²
