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 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.

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.
