Problem Analysis

We are given a trapezoid with bases measuring 6 cm and 10 cm, inscribed in a circle. The center of this circle is located on the larger base. We need to find the area of the trapezoid.

Solution

To find the area of the trapezoid, we can use the formula:

Area = (sum of the bases) * (height) / 2

In this case, the sum of the bases is 6 cm + 10 cm = 16 cm. We need to find the height of the trapezoid.

Since the trapezoid is inscribed in a circle, we can use the properties of inscribed angles to find the height. The height of the trapezoid is equal to the radius of the circle.

Let's denote the radius of the circle as R. According to the properties of inscribed angles, the height of the trapezoid is equal to the perpendicular distance from the center of the circle to the smaller base of the trapezoid.

Using the Pythagorean theorem, we can find the height of the trapezoid:

R^2 = (6/2)^2 + h^2

Simplifying the equation, we get:

R^2 = 9 + h^2

Since the center of the circle is located on the larger base of the trapezoid, the radius of the circle is equal to half the difference between the lengths of the bases:

R = (10 - 6) / 2 = 2 cm

Substituting the value of R into the equation, we can solve for h:

2^2 = 9 + h^2

4 = 9 + h^2

h^2 = 4 - 9

h^2 = -5

Since we cannot have a negative value for the height, it means that the trapezoid cannot be inscribed in a circle with the given dimensions. Therefore, it is not possible to calculate the area of the trapezoid.

Conclusion

In conclusion, the trapezoid with bases measuring 6 cm and 10 cm cannot be inscribed in a circle. Therefore, it is not possible to calculate the area of the trapezoid.
