Question

PLEASE HELP [Area & Circumference]

Answer 1

Answer:

1.

circumference=diameter ×pi

=(29×2)× pi

=59×pi

area= pie × radius²

=pi×29²

=841pi

2.

circumference =pi×16.5

area=pi×8.25²

3.

153.94÷pi

radius=square root of 49.00062388

=7.000044563

times by 2

=14.00008913

4.

28.27÷pi

8.998620482=diameter

divide by two to find radius

4.499310241

then square

20.24379265

then times that by pi

=63.59775026
