    Study Notes

    Area Formulas

    • Area formula for a square is represented as A = s², where s is the length of the side.
    • For a rectangle, area is calculated using A = lw, with l being length and w being width.
    • The area of a parallelogram is given by A = bh, where b is the base and h is the height.
    • To find the area of a triangle, use A = 1/2bh, which is half the product of the base and height.
    • The area of a trapezoid can be determined with A = 1/2h(b1 + b2), where h is height and b1, b2 are the lengths of the two bases.
    • For a rhombus, area is calculated as A = 1/2d1 x d2, where d1 and d2 are the lengths of the diagonals.
    • The area of a kite is also given by A = 1/2d1 x d2, similar to the rhombus.

    Circle Measurements

    • The circumference of a circle can be calculated using either C = πd or C = 2πr, where d is the diameter and r is the radius.

    Arc Length

    • In a circle, the arc length is directly proportional to the angle it subtends at the center. The ratio of the arc length to the circumference equals the ratio of the arc's angle measure to 360 degrees.
