Answer 2

Finding the Radius of a Circle

To find the radius of a circle given the lengths of two parallel chords and the distance between them, we can use the following formula:

Radius = (Distance between chords) / 4 + (Sum of the squares of the chord lengths) / (8 * (Distance between chords))

In this case, we are given that the lengths of the two parallel chords are 48 cm and 24 cm, and the distance between them is 12 cm. Let's substitute these values into the formula:

Radius = (12 cm) / 4 + (48 cm^2 + 24 cm^2) / (8 * 12 cm)

Simplifying the equation:

Radius = 3 cm + (2304 cm^2 + 576 cm^2) / 96 cm

Radius = 3 cm + 2880 cm^2 / 96 cm

Radius = 3 cm + 30 cm

Radius = 33 cm

Therefore, the radius of the circle is 33 cm.
