The sum of the internal angles of any regular polygon is (n - 2) x 180 degrees. Since a triacontakaihexagon has 36 sides, the sum of the internal angles of a triacontakaihexagon has a sum of internal angles of (36 - 2) x 180 = 6120 degrees.
The area of the square is 18 cm2 The area of a square is: area = side2 By Pythagoras: side2 + side2 = diagonal2 ⇒ 2 side2 = diagonal2 ⇒ side2 = diagonal2 ÷ 2 ⇒ area = diagonal2 ÷ 2 diagonal = 6cm, so: area = (6 cm)2 ÷ 2 ⇒ area = 18 cm2
Well, honey, the external terms of a ratio are the first and last numbers in the ratio, while the internal terms are the second and third numbers. So if you've got a ratio like 2:5, the external terms are 2 and 5, and the internal terms are... you guessed it... 2 and 5. Math can be a real hoot, can't it?
Its Area = pi * (radius ^2 - height^2)
Area of circle = pi x (radius)2 pi= 3.1416 radius = diameter/2 = 17/2=8.5cm Therefore, Area= 3.1416 x (8.5)2 Area= 226.98 sq.cm.
