Oh, dude, like, the area of a circle is π times the radius squared, right? So, if the diameter is 200 m, the radius is half of that, which is 100 m. Just plug that into the formula, and you get an area of 31,415.93 square meters. Easy peasy, lemon squeezy.

What is the circumference of a circle whose diameter is 200 m?
The diameter times pi. Pi is approximately 3.1416. Scientific calculators also have a button to quickly access the value pi.
If a circle has a radius of 100 miles what is the diameter?
Its diameter will be: 2*100 = 200 miles
If the radius of a circle is 100 cm then the diameter of the circle is how many meters?
2 meters
What is the circumference of a circle circumscribed about a square with a perimeter of 40?
Assuming you mean that the circle is touching all 4 corners of the square: If the perimeter of the square is 40, then each side of the square is 10 (40/4=10). You could find the diameter of the circle by breaking the square up into 2 triangles, drawing a diagonal line through the square. Using pythagorean's theory (a^2+b^2=c^2), we know legs 2 and b (they are each one side of the square, so: (10^2+10^2=c^2). 10^2 is 100, therefore it is (100+100=c^2). (200=c^2) (√200=c) and the √ of 200 is about 14.142, meaning that the diameter of the circle is √200, which is the same as 10√2, (or approximately 14.142). You multiply the diameter of a circle by pi to get the circumference of a circle. Therefore, the exact answer is (10√2)(π), which would be approximated at 44.42882938158366247015880990 units, where π is pi.
What is the area of a square inside a circle where the radius of the circle is 10centimetres?
314.16 cm2 This is not what I get... I get 200cm^2 and here is my reasoning: The diameter of the circle is the same as the diagonal of the square so... 2r = diagonal of the square Diagonal of the square is the hypotenuse of two triangles that form the square. In a right triangle, a^2 +b^2=c^2 where c is the hypotenuse (diagonal of the square) We can then write... 2r = c we know that r= 10 so... 2(10)= c therefore c=20 back to pythagorean theorum... a^2+b^2=20^2 since it is a square, both sides are equal so b^2 must = a^2 or a^2+b^2= a^2+a^2 or (b^2+b^2) so we can write a^2 + a^2 = 20^2 2a^2= 400 ----- therefore a^2= 200 Then, a = square root of 200 but we would multiply a times itself anyway (side x side = area) so the correct answer would be 200 cm^2.
What is the area of a circle whose diameter is 200 m hectare?
Using 3.14 as Pi the area of circle is: 31400.0
What diameter is a circle area of 200 acres?
A circle with an area of 200 acres has a diameter of: 3,331 feet.
What is the area of a circle with a diameter of 200 feet?
Using 3.14 as Pi the area of circle is: 31400.0
What is the diameter of a circle that has an area of 200 pi squared?
d = 28.3
What is the area of a circle is the diameter is 16?
Divide the diameter by 2 to get the radius. Then use the formula for the area of a circle: area = pi x radius2.
What is the circumference of a circle whose diameter is 200 m?
The diameter times pi. Pi is approximately 3.1416. Scientific calculators also have a button to quickly access the value pi.
What is the radius in feet of the 200 diameter circle?
100. The radius is 1/2 of the diameter.
If a circle has a radius of 100 miles what is the diameter?
Its diameter will be: 2*100 = 200 miles
What is the area of a circle if the diameter is 400 feet?
Area = pi times radius2 where radius = 200 feet therefore area = pi times 2002 Area = 125 663.7 feet2
If a circle has an area 628mm what is the diameter?
Area = pi * radius2 628mm2 = 3.14 * radius2 dividing by pi (approximately 3.14) 200mm2 = radius2 Taking the square root of 200, 14.14mm is the radius. The diameter is twice the radius, so the diameter is 28.28mm.
If the diameter of a circle is 200 what is it's radius?
It is 100 units.
What is the approximate area of a circle with 16 cm diameteer?
Divide the diameter by 2, to get the radius. Then use the formula for the area of a circle:area = pi x radius squared
