No. Assuming just talking about the base area and not the total surface area as no height of the pans is given: radius = diameter/2 Area_circle = π x radius2 = π x (20 in/2)2 = 100π sq in ≈ 314 sq in Area_square = side2 = (18 in)2 = 324 sq in ⇒ square of 18 in has larger area than a circle of diameter 20 in.
Well, since the formula for the area of a circle is Pi (3.14) times the radius squared, you can use substitution to get an equation that looks like this: 3.14(102) ...which can be simplified to 3.14(100), which can be simplified to come up with the answer of 314 square units.
3.14*102 = 314 square centimeters
Diameter = 314/pi feet
The circumference is 62.815 units.
The circumference of a circle can be calculated using the formula C = πd, where C is the circumference, π is a constant approximately equal to 3.14159, and d is the diameter of the circle. In this case, the diameter is 100 feet, so the circumference would be C = π(100) = 314.159 feet.
Using pi as 3.14 it works out that the diameter is 20 cm
If you mean 3.14 for pi then the circumference is: 7*3.14 = 21.98 cm
It's simple, just multiply de diameter of the circle by the pi number: 3.141592653.... the result is 31.14 cm, or 314 milimeters.

Circumference = 314 inches implies radius = 49.97 inches and so area = 7846.02 sq inches (approx).
divide the circumference by pie (3.14) and the answer would be the radius. for example circumference = 314 pie = 3.14 so 314 divide by 3.14 = 100 so the radius = 100
