Answer:

20.25 m²

Step-by-step explanation:

the area (A) and circumference (C) of a circle are calculated using the formulae

C = 2πr and A = πr² ( where r is the radius )

calculate the radius using the formula for circumference

2πr = 9π ( divide both sides by 2π )

r =  =  = 4.5, hence

A = π × 4.5² = 20.25π m²

Answer:

[tex]Solution,\\Circumference=9\pim \\Diameter(d)=9\pi /\pi =9m\\Radius(r)=9m/2=4.5m\\Now,\\ Area=\pi r^{2} \\Area=\pi *(4.5m)^{2} \\Area=\pi *20.25m^{2} \\Area=20.25\pi m^{2}[/tex]
