The Diameter is the distance from one side of the circle all the way to the other side. The Radius is half the distance in a circle. Simply put: 40cm = Diameter 20cm = Radius (Half the distance) :)
The Answer is 20cm because you divide the diameter by 2 and then it should be your answer EX: 20/2=10, 102= Radius
This cannot be properly answered because a 20 cm radius equates to a 40 cm diameter. Also, a 50 cm diameter means a 25 cm radius.
The radius of a circle is half of its diameter
1/2 of the diameter
That depends what you mean with "a 20 cm. circle". If 20 cm. is the radius, you already have the answer. If 20 cm. is the diameter, the radius is half the diameter. (10cm)
WOW really? It would be 20cm
The Diameter is the distance from one side of the circle all the way to the other side. The Radius is half the distance in a circle. Simply put: 40cm = Diameter 20cm = Radius (Half the distance) :)
A circle with a radius of 10 cm has an area of 314.16 square cm
The Answer is 20cm because you divide the diameter by 2 and then it should be your answer EX: 20/2=10, 102= Radius
This cannot be properly answered because a 20 cm radius equates to a 40 cm diameter. Also, a 50 cm diameter means a 25 cm radius.
The diameter of a circle is twice its radius
The radius of a circle is half the diameter so if the radius of a circle is r, then the diameter is 2r.
The diameter of a circle is twice its radius
The radius of a circle is always half of the diameter. If the diameter is 85.4, the radius is 42.7.
The radius of a circle is half of the diameter, so the radius of a circle with a diameter of 14in is 7in.
A = 1,257 cm2
