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

What would be the perimeter of a farm fence 300 meters on 2 side's 450 meters on one side and 650 meters on the other?
300+300+450+650 = 1700 metres
How many metres less than half a kilometre is 150 metres x 3?
Oh, dude, you're hitting me with the math questions, huh? So, 150 meters times 3 is 450 meters. Half a kilometer is 500 meters, so 500 minus 450 equals 50. So, 150 meters times 3 is 450 meters less than half a kilometer. Math class dismissed!
450 square meters in square feet?
450 sq metres = 4844 sq feet.
How do you convert 450 millimeters in meters?
Divide by 1000.
Is 4 meters greater than 450 centimeters?
