The answer depends on what the 20 cm refers to.
If the diameter of a circle 20 cm is tripled the area will increase from 314.2 cm2 to 2,827 cm2
The circumference of a circle with a diameter of 20 centimeters is: 62.83 cm (diameter x Pi = circumference).
20 cm
The radius of a circle is the distance from its center to any point on its circumference. If the radius is given as 20 cm, this means that every point on the circle is 20 cm away from the center. In terms of diameter, this would make the diameter 40 cm, as the diameter is twice the radius.
The Lateral Area of a cylinder with diameter of 12 cm and a height of 20 cm is equivalent to 0.075 square meter. Diameter of 12 cm is equals to 0.06 meter in radius and height of 20cm is equals to 0.2 meter
If the circumference is 20 cm then the diameter is 6.366 cm
The area of a circle with a diameter of 20 cm is: 314.2 cm2
If the circumference of a circle is 20 cm, the diameter will be: 6.37 cm (D = c divided by Pi).
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)
Radius: square root of (12320/20*pi) = 14.00281721 cm Diameter: 28.00563442 cm
20 cm
If the diameter of a circle 20 cm is tripled the area will increase from 314.2 cm2 to 2,827 cm2
A cylinder with a diameter of 20 cm and a length of 7 cm has a volume of 2,199.11 cm3
The Answer is 20cm because you divide the diameter by 2 and then it should be your answer EX: 20/2=10, 102= Radius
