The area of a circular table with an 18-foot circumference is 25.783 feet2

2826 square feet

Radius is 30 inches.

The radius is 30 inches.

the formula for the area of a circle is pi times r squared (sorry this website does not work today for presenting this better) so 2826 = pi times r squared so dividing through on both sides bi pi gives you: 2826 divided by pi = r squared so r is the square root of (2826/ pi) 2826/pi = 899.5437384 so r is the square root of 899.5437384 = 29.99239468 r = 29.99 (to 2 decimal places)

Circumference = 72*pi

The country code and area code of Rastenfeld, Austria is 43, (0)2826.

Area = (Circumference)2/(4*pi)

Area = circumference squared... You do circumference divided by 4,... and then divide that by 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

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.
