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
