What is the formula for the area of a circle?
A = π d
A = π r3
A = π r2
A = π d2
10
Triangle area formula
A=\frac{bh}{2}
A=\frac{1}{2}b+\frac{1}{2}h
A=\frac{1}{2}bh
A=\frac{b+h}{2}
11
Trapezoid area formula
A=\frac{\left(b_1+b_2\right)h}{2}
A=\frac{1}{2}b_1b_2h
A=\frac{1}{2}\left(b_1+b_2\right)h
A=\frac{b_1+b_2}{2}h
