Question

what is the area of a circle whose circumference is equal to 440 metres?

Answer 1

Answer:

$15406.2m²$

Answer 2

Given :

Circumference of circle : 440m

Formula for Circumference of circle : 2πr

This means ;

440m = 2πr

$\frac{440 \times 7}{22 \times 2} = r \\ \\ 10 \times 7 = r \\ \\ \:\boxed{\mathtt{ r = 70}}$

Area of circle : πr²

Area : 22/7×70×70

Area of circle : 15,400m²
