Question

Choose correct alternative answer and fill in the blanks.
(i) Radius of a circle is 10 cm and distance of a chord from the centre is 6 cm. Hence
the length of the chord is
(A) 16 cm AB) 8 cm (C) 12 cm (D) 32 cm
of triangle is called the​

Answer 1

Answer:

Answer is 12 cm . Because the length of chord from center is 6cm and we know that diameter is the longest chord So,. we can find it by multiplying it by 2 .and also we know that Diameter =2 radius

2×6=12 cm .

Hope it helps you .Thank you

Answer 2

Answer:

Let the circle be with center O and radius 10 cm. Let there be a chord AB

Draw a perpendicular from O on AB to meet at P. The perpendicular from the center divides the chord in two halves. Given, OP=6cm

Thus, In △OAP, Using Pythagoras theorem

OA
