Question

The spinner of the compass is two congruent isosceles triangles connected by their bases as shown in the diagram. The base of each of these triangles is 2 centimeters and the legs are 5 centimeters.

If the metal used to construct the spinner costs $13.25 per square centimeter, how much will it cost to make this part of the compass? Round to the nearest cent.

    Answer:

    fff

    Step-by-step explanation:

    By pythagorean theorum we calculate the height:

    \sqrt{5^2-1^2}

    =\sqrt{24} = height of triangle

    area of triangle = base * height

    area = 2*\sqrt{24}

    There are two triangles so:

    2*2*\sqrt{24}=4\sqrt{24}

    Multiply this by 13.25 to get total cost:

    =$259.65
