Answer 2

here we have to compute the area of a circle whose diameter is 16 feet, so we have:
\[\large A = 3.14 \times {R^2}\]
and R = D/2, where D, as usual, is the diameter

Answer 3

3.14*16^2?

Answer 4

3.14*8^2=...?

Answer 5

200.96

Answer 6

ok!

Answer 7

now, since the area of the room is:
16*16=256 feet^2
then we have to compute this difference:
\[\large 256 - 200.96 = ...?\]

Answer 8

55.04!

Answer 9

ok!
