Question

A chord of length 24 m is at a distance of 5 m
from the centre of a circle. Find the radius of
the circle.​

Answer 1

Answer:

Radius of the circle = 13 cm

Area of the circle = 531.14 cm²

Step-by-step explanation:

Given,

• Chord of a circle = 24 cm.

• Distance of chord from center of the circle = 5 cm

∴ Radius of the circle (r) = [(24/2)²+5²]¹⁾² = [144+25]¹⁽² = 13 cm.

Area of the circle = 3.14 × 13² = 531.14 cm²
