Circumference is equal to Pi times the Diameter C= (pi) X D C= 3.14 X 6 C= 18.85
3.14 x 3.14 = 9.8596
Cosec x = -2 => sin x = -0.5 The primary solution is x = -pi/6 radians. Therefore the solutions are: 2n*pi - pi/6 and (2n+1)*pi + pi/6 for all integer n.
Are is found by (pi)r^2 or pi times the "radius squared" in this case it is (pi) x 6 squared = (pi) 36 Your answer 36 (pi) squared feet As mentioned above, the formula is A = Pi x R² where Pi = 3.1416 and R² is the radius multiplied by itself. Now, to apply the formula: A = 3.1416 x (6 x 6) = 3.1416 x 36 = 113.0976 sq ft.
2 x pi x r (radius) or pi x d (diameter) equal circumference of a circle.
