Area = pi * r² ; and Circumference = pi * 2 * r. So Area = pi * 10 = pi * r². Divide both sides by pi:

  • r² = 10 --> r = √10
  • Circumference = pi * 2 * √10

The circumference of circle whose diameter is 10 is: 31.42 (diameter x Pi = circumference).


The area of a circle when the circumference is 10 inches is: 7.96 square inches.


A circle has a radius, diameter and circumference, not a base and a height.


The area of a circle whose diameter is 10 cm is: 78.54 cm2


Circumference of circle: 2*pi*10 = 62.832 cm rounded to 3 decimal places



There is a problem here. A circle with a 7-foot diameter has a circumference of 21.99 feet, not 10 feet.If the circumference is 10 feet, that would make the diameter 3.183 feet.


Circumference = (pi) x (diameter) = 10 pi = 31.416 yards (rounded)


We know that the area of a circle is pi * r2. We also know that the circumference of a circle is pi * d. Therefore, when you know the circumference of a circle and want to know the area, divide the circumference by pi to give you the diameter of the circle, divide the diameter by 2 to give you the radius, square the radius and then multiply by pi to get the area. So, 10/pi = 3.183. 3.183/2 = 1.5915. 1.59152 = 2.533 2.533 * pi = 7.958 to 3 decimal places. The area of your circle is therefore 7.958cm2.


The circumference of a circle with a diameter of 10 is: 31.416. (Circumference = Pi x diameter)


The circumference of a 10-inch diameter circle is: 31.42 inches.



Divide the circumference of 62.8 by 2*pi to find the radius which is about 10 units Area of the circle: pi*10*10 = 100*pi square units



That's easy - 10. Or did you mean circumference or area?


The circumference of a 10 inch circle is: 31.416 inches(circumference = diameter x pi).


The formula for circumference is 2 x pi x radius. For a circle of 10 feet, the cirumference would be 62.8 feet. The formula for area is pi x r2. For a circle of 10 feet, the radius would be 314.16 ft.


If you read the question properly, you will see that the area will be 10 pi.


This circle's area would be 78.54 units squared.


The circumference of a circle with a 10 millimeter diameter is about 31.42 mm


The circumference of a circle with a radius of 10 inches is about 62.83 inches.

Circumference of circle: 10*pi = about 31.4 inches


The circumference of a 10-inch diameter circle is: 31.4 inches.


you have to quote the diameter or radius or circumference of the circle to calculate the area. If diameter 78.53. If radius 314.15. If circumference 7.95
