Question

The radius of a circular sign is 12 inches. Equal parts of the sign are painted red and yellow. How many square inches are painted each color l? Use 3.14 for PI

Answer 1

here im right

trust me

Answer 2

226.08 square inches

Explanation:

Area of a circle is given by

`A=\pi r^(2)`

Where r is the radius and r is the area.

For this case, since one half is painted yellow and another red, then the area for each paint will be given by

`A=0.5\pi r^(2)`

Substituting 12 inches for r then

`A=0.5\pi 12^(2)=226.08 in^(2)`

Therefore, each paint occupies approximately 226.08 square inches
