Question

What is the area of a circle whose circumference is 104 7.2 metre?

Answer 1

Answer:

Step-by-step explanation:Given

$2\pi r=104.72 \implies  r = \frac{104.72}{3.14 \times 2} = 16.67 m\\area = \pi r^{2}  = 3.14 \times 16.67 ^2 =  873.11 m^2$

Answer 2

Answer:

Step-by-step explanation:

2πr = 1047.2 m

r = 1047.2 / 2π = (10472 x 7) / 440 = 166.6 m

Area of circle = πr²

                       =  π (166.6)² = 87231.76 m²
