Unit 6 Test Review (Geo)

$$A = l \times w$$ where A is the area, l is the length, and w is the width.

$$A = \pi r^2$$ where A is the area and r is the radius.

The diameter is the distance across the circle through its center, equal to twice the radius.

$$C = 2\pi r$$ where C is the circumference and r is the radius.

$$A = \frac{1}{2} b h$$ where A is the area, b is the base, and h is the height.

The diameter is twice the radius: $$d = 2r$$ .

$$A = b h$$ where A is the area, b is the base, and h is the height.

$$A = \frac{1}{2} (b_1 + b_2) h$$ where A is the area, b_1 and b_2 are the lengths of the two bases, and h is the height.

$$A = s^2$$ where A is the area and s is the length of a side.

$$V = l \times w \times h$$ where V is the volume, l is the length, w is the width, and h is the height.
