169/pi = 53.79437...
25.78310078 or about 26 square units
If its diameter is 26 inches then its circumference = 26*pi = 81.681 inches to 3 decimal places
If a circle has a circumference of 26 the diameter is: 8.276
If the pool is 26 feet around, then its circumference is 26 feet. If the pool is 26 feet across, then its circumference is 81.7 feet.
radius=13 area=40.82 circumfrence=8.28025477707
Area = (Circumference)2/(4*pi)
area = π x radius2 ⇒ radius = √(area ÷ π) circumference = 2π x radius ⇒ circumference = 2π x √(area ÷ π) ⇒ circumference = √(4π2 x area ÷ π) ⇒ circumference = √(4π x area) So knowing the area, the circumference can be calculated by taking the square root of the area multiplied by 4 times π Example: What is the circumference of a circle with area 78.54cm2 Circumference = √(4π x area) = √(4π x 78.54cm2) ~= 31.42cm
Area = circumference squared... You do circumference divided by 4,... and then divide that by Pi.
Circumference = 2Ï€r so r = circumference/2Ï€ Then area = Ï€r2
The area of a circle with a circumference of 9.42 is about 7.06.
circumference doesn't matter when solving for area..
