Answer 2

if diameter is 22 meters, then the radius is 11.

A= π r²

Answer 3

Use a 3.14 approximation for π

Answer 4

ok multiply 11*11 and you get 121 and now you multiply 3.14 and get 379.94

Answer 5

is it correct

Answer 6

Yes, totally !

Answer 7

but its not in the question thats what got me confused

Answer 8

help me @zpupster

Answer 9

Ohh, you have to use 22/7 for π.
So then the radius is still 11, and so A = π r² = (22/7) × 11²
= (22/7) × 121
= 121 × (22/7)
= (121 × 22)/7
= 2662 / 7
= 380 and 6/7 .
