The area of a circle is (pi) times (the radius)2. The radius of the given circle is 1/2 of the diameter = 20m. Area = (pi) times (20)2 = 400(pi) = 1,256.64 square meters(rounded)
A cone that has a radius of 20m and a height of 25m has a volume of 10471.98m3
Volume = 753.98224m3
20m x 20m = 400 metres2
No, 20K does not equal 20M. "K" stands for thousand, so 20K equals 20,000. In contrast, "M" stands for million, meaning 20M equals 20,000,000. Therefore, 20K is significantly smaller than 20M.
