The perimeter of a circle is called the circumfernece.
Circumference = Pi * d, where d is the diameter of the circle.
Area = Pi * r2 , where r is the radius of the circle.
=> d*Pi = 450
{divide by Pi on both sides}
=> d = 450/Pi
{r = d/2, use substiution}
=> r = 225/Pi
{substitute in to Area formula}
=> Area = Pi * (225/Pi)2
{simplify}
=> Area = 2252/Pi
Area of a circle with a circumference of 450m = 16114.43799m2
300+300+450+650 = 1700 metres
450 sq metres = 4844 sq feet.
Divide by 1000.

4.50 × 102 nanometers.
300+300+450+650 = 1700 metres
It is: 15 meters by 30 meters
Square inscribed a 30 ft diameter has a diagonal equal to 30 ft. Use the Pythagorean theorem, and side^2 + side^2 = 30^2 2s^2 = 900 s^2 = 450 side length = square root of 450, simplify 15sqrt(2) = s Area = s^2 = 450 square feet Perimeter = 4s = 4*15*sqrt(2) = 60 times the square root of 2
450 meters is 1,476.4 feet.
The formula, when the radius is known, is: A = PI(r)2 A circle with a radius of 450 mm has an area of 636,172.51 square mm.
There are 4.5 meters in 450 centimeters.
450 centimeters = 4.5 meters
450 square feet = 41.806368 square meters
Answer: 450 ' = 137.16 meters.
A foot is 0.3048 meters. So that would give you 137.16 meters.
450 (square feet) = 41.806368 square meters.
450 square feet is equivalent to 41.8 square meters.
