The area is 113.1 cm2
area of circle is πr² (3.14)(6)² 3.14 * 36 = 113.45 cm² ■
It is approx 113.1 cm squared.
The area of a circle is calculated with the formula πr2, where r is the radius. Therefore, the area of a circle with radius 6cm would be π(6)2 = (36)π, or approximately 113.097 square centimeters.
If the diameter is 12 cm the radius is 6 cm.
The answer depends on what characteristic of a half circle you want to calculate: its area or perimeter or something else.
i suppose it should be 6 centimeters. The area of a circle is pi*r2 with pi = 3.1415.... thus A = 3.1415*(6)2 = 113.097 cm2 = 0.011309 m2
A circle with a radius of 6 units has an area of 113.1 square units.
Area = pi*radius squared
C = ~37.7 cm
Area of a circle: pi*radius*radius
A cone with a radius of 6 centimeters and a slant height of 9 centimeters will have a total surface area of approximately 282.74cm2
