The answer depends on what characteristic of a half circle you want to calculate: its area or perimeter or something else.
Area of circle = pi x radius x radius where pi = 3.14159 If radius = 6 cm then Area = 3.14159 x 6 x 6 sq cm = 113.097 sq cm
Area = pi*radius squared
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
If it is a circle you are referring to the Area if the circle would be (pi)x(r^2) and the radius is 6 so the answer would be 36(pi)
It is approx 113.1 cm squared.
Well, honey, if the diameter is 12 cm, all you gotta do is cut that bad boy in half to get the radius. So, the radius would be 6 cm. Easy peasy lemon squeezy!

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
The area of a circle can be calculated using the formula A = πr^2, where r is the radius of the circle. Since the diameter is twice the length of the radius, the radius of a circle with a diameter of 6 cm is 3 cm. Plugging this value into the formula, we get A = π(3)^2 = 9π cm^2. Therefore, the area of a circle with a diameter of 6 cm is 9π square centimeters.
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.
Area of circle = pi x radius x radius where pi = 3.14159 If radius = 6 cm then Area = 3.14159 x 6 x 6 sq cm = 113.097 sq cm
A circle with a radius of 6 units has an area of 113.1 square units.
the area of a circle is pi times the radius squared. The diameter is 12, so the radius is 6 (half of the diameter). Therefore, the area is pi times 6 squared, which is 36 pi square centimeters. Also, if you want the answer in decimal, it's 113.09733552923255658465516179806 square centimeters.
C = ~37.7 cm
Area = pi*radius squared
Area of a circle: pi*radius*radius
