Answer:
226.195 cm²
In terms of pi:
A = (π · 12²) ÷ 2
Explanation:
A = πr²
A = π · 12²
A = π · 144
A = 452.39
452.39 ÷ 2
226.195
72pi
The formula for the area of a circle is pi*r^2
Since three radius is 12, then it’s pi*12^2
pi*12^2= 144 x pi but that’s the area of a whole circle so divide by 2 and you get:
