Question

I worked out this problem (but what I came up with was what that google photo says. I checked multiple times but no luck. Can I get some help?

Answer 1

It is 36 because ti didn't multiplied by the π

so the formula for area of the circle is A=πr2
 
so our r is 6 so 6*6 is 36 so we still need to do π so the answer is 

π*36 or 36π for this but the total area is 113.1

answer = 36π
