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.
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
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.
C = ~37.7 cm
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.
Area = pi*radius squared
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
