Perimeter of a Semicircle  \(\pi\) x r + 2 x r 
Perimeter of a Quarter Circle  \(\frac{1}{2}\) x \(\pi\) x r + 2 x r 
Area of a Circle  \(\pi\)\(r^2\) 
Area of a Semicircle  \(\frac{1}{2}\) x \(\pi\) x \(r^2\) 
Area of a Quarter Circle  \(\frac{1}{4}\)\(\pi\)\(r^2\) 
Area of a Rectangle  base x height 
Area of a Triangle  \(\frac{1}{2}\) x base x height 
Area of a Parallelogram  base x height 
Area of a Trapezium  \(\frac{1}{2}\)(a + b)h 
Area of a Sphere  4\(\pi\)\(r^2\) 
\[a^2\]  a x a 
\[b^3\]  b x b x b 
\[4d^2\]  4 x d x d 
\[2e^3\]  2 x e x e x e 
\[4y^2  y\] when y = 3, y = ?  (4 x y x y)  y = (4 x 3 x 3)  3 = 33
