What are the formula(s) for the circumference of a circle?

•  $C=2\pi r$  

•  $C=\pi d$  

•  $C=\pi r^2$  

What is the area formula for a trapezoid

• $A=\frac{1}{2}h\left(b_1\div b_2\right)$

• $A=\frac{1}{2}h\left(b_1+b_2\right)$

• $A=\frac{1}{2}h\left(b_1\times b_2\right)$

• $A=\frac{1}{2\ }h\left(b_1-b_2\right)$
