Calculate the area of a circle whose diameter is 6 cm.
| January 16, 2021 | education
The area of a circle can be found using the formula:
S = pi * r ^ 2,
where S is the area of the circle; pi = 3.14; r is the radius of the circle.
1. Since the radius of the circle is half the diameter, then:
r = 6 cm / 2 = 3 cm.
2. Substitute the values into the formula:
S = 3.14 * 3 ^ 2 = 28.26 cm 2.
Answer: the area of the circle is 28.26 cm 2.
