Answer 1

The formula for the area of a circle is:

A = πr^2

where A is the area and r is the radius.

In this case, the radius is 9 millimeters. We can substitute this value into the formula and use 3.14 or 22/7 for π:

A = 3.14 x 9^2

A = 3.14 x 81

A ≈ 254.34 mm²

Rounded to the nearest tenth, the area of the circle is about 254.3 mm².

Answer 2

254.3

Explanation:

A= 3.14*9^2=3.14*81=254.34

254.34 rounded is 254.3
