The area would be 78.53 squared inches.
Formula:
PI (x) Radius squared = Area
Radius is half of the diameter of the circle. So the radius is 5 Inches. (10 divided by 2 = 5)
3.14 x 5 squared = Area ---> 3.14 x 25 = 78.53981634

The area of a circle when the circumference is 10 inches is: 7.96 square inches.
25 square inches.Method:The area of complete circle is Pi x radius2 which is 3.14159 x 5 x 5, = 78.53982 sq ins.The circumference of a circle is Pi x diameter, which is 3.14159 x 10, = 31.4149 ins.But the arc is only 10/31.4159ths of the length of the full circle (10 divided by 31.4159 is 0.3183).So the area of sector with an arc 10 inches in length is: area of full circle (78.53982) x 0.3183 = 25.The above figures are only to a few significant decimal places. If you do the computations on a computer or a calculator the answer will come to exactly 25
Circumference=(pi)Xdiameter, diameter=Circumference/(pi)=(10in)/(3.14)=3.183in Area=(pi)d2/4=(pi)[Circum/(pi)]2/4=Circum/(4pi)=0.7957~8 square inches.
The area of a circle with a diameter of two cm is about 3.1416 cm.
The area of a circle if the diameter was s 7ft is 38.48ft
