Question

The distance between two parallel tangents of a circle is 10 cm. Then the radius of the circle is

• A. 10 cm
• B. 8 cm
• C. 5 cm
• D. 12 cm

Hint:

The distance between two parallel tangents of a circle is equal to twice the radius.

Answer 1

The Correct Option is A

Step 1: The distance between two parallel tangents of a circle is twice the radius. \[ \text{Distance between tangents} = 2r \] Step 2: Given that the distance is 10 cm: \[ 2r = 10 \] Step 3: Solving for \( r \): \[ r = 5 \, \text{cm} \] Thus, the correct answer is \( \boxed{5 \, \text{cm}} \).
