Commit to memory the two circle equations
C = 2 pi r
A = pi r^(2)
We required the second eq'n
A = pi 10^(2)
A = 3.14 X 100
A = 314.00 sq. ft.

What is the diameter of of a circle when the area is 78.5?
Diameter of circle: 2 times square root (78.5/pi) = 10 units rounded up
What is the area and circumference of a small circle 10 inches in diameter?
Area = Pi multiplied by the radius squared Circumference = Pi multiplied by the diameter r = 10 in./2 = 5 in. A = (3.1415)(5 in.)(5 in.) = 78.54 in.2 C = (3.1415)(10 in.) = 31.42 in. Therefore, a small circle with a diameter of 10 inches has an area of about 78.54 inches squared and a circumference of about 31.42 inches.
What is the area of circle with a 10 ft radius?
Area of a circle = pi*radius2 Area = 314.159 square feet to 3 decimal places.
What is the area of circle with a radius of 10 feet?
Area = pi R2 = 100 pi = 314.16 square feet (rounded)
If the circumference of a circle is 10 inches what is the diameter?
If the circumference of a circle is 10 inches, the diameter is: about 3.183 inches. (circumference divided by Pi = diameter)
