Answer:

125.66cm²

Step-by-step explanation:

so you need to find the area of the big circle and subtract it from the area of the small circle

area of a circle= π r²

small circle: substitute in what you know

a= π x 3²

a= 28.2743

big circle: substitute in what you know

a= π x 7²

a= 153.9380

now do 153.9380-28.2743=125.6637

now round this number to the nearest hundredth:

125.66cm²
