Find the radius of the circle if the length of the chord is 8 cm and the perpendicular distance from the center of the circle is 3 cm
Show answer & explanation
Correct answer: B
Explanation
Chord = 8 cm
Distance from the center = 3 cm
r² = (Chord/2)² + Distance²
r² = (8/2)² + 3²
= 4² + 9
= 16 + 9
= 25
r = 5 cm
