distance of centre from p = √31 cm
Step-by-step explanation:
Let draw OM ⊥ AB & ON ⊥ CD
OM ⊥ AB => AM = BM = AB/2 = 8/2 = 4 cm
ON ⊥ CD => CN = DN = CD/2 = 10/2 = 5cm
OA = OB = Radius = 6 cm
OM² = OA² - AM² = 6² - 4² = 36 - 16 = 20
ON² = OD² - DN² = 6² - 5² = 36 - 25 = 11
OMPN is a rectangle
=> OP² = OM² + ON²
=> OP² = 20 + 11
=> OP² = 31
=> OP = √31
distance of centre from p = √31 cm
