The area of the circle is 113.04 cm²
Step-by-step explanation:
The given information are,
The diameter of the circle = 12 cm The diameter must be converted into radius.
Radius = diameter / 2
Radius = 12/2 = 6 cm
Now, the formula for area of the circle is given by πr²
where,
r is the radius of the circle. π has the default value 3.14
To calculate the area of circle:
Substitute r=6 and π=3.14,
Area of the circle = (3.14) * (6²)
⇒ 3.14 * 36
⇒ 113.04 cm²
The area of the circle is 113.04 cm²
