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.
This circle's area would be 78.54 units squared.
The area of a circle whose diameter is 10 cm is: 78.54 cm2
Circumference = (pi) x (diameter) = 10 pi = 31.416 yards (rounded)
The circumference of circle whose diameter is 10 is: 31.42 (diameter x Pi = circumference).
Using 3.14 as Pi the area of circle is: 0
The area of a circle when the circumference is 10 inches is: 7.96 square inches.
This circle's area would be 78.54 units squared.
Circumference of circle: 2*pi*10 = 62.832 cm rounded to 3 decimal places
The area of a circle whose diameter is 10 cm is: 78.54 cm2
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)
Using 3.14 as Pi the area of circle is: 78.5
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.
If a circle's diameter is 10, the circumference is: 31.416
Area = 78.54 cm2Circumference = 31.42 cm
