Question

A chord 6.6cm long is 5.6cm from the centre of a circle, calculate the radius of the circle​

Answer 1

chord 30cm long is 20cm from the centre of a circle calculate the length of a chord ... Find the length of an arc of a circle of radius 5.6cm which subtends an angle of 60°at the centre of the circle of the ...

Answer 2

Answer: radius = 6.5 cm

Step-by-step explanation:

The distance from the center to the chord is measured at its perpendicular.

Therefore we can use Pythagorean Theorem to find the radius.

r² = 5.6² + 3.3²

r² = 31.36 + 10.89

r² = 42.25

`√(r^2)=√(42.25)`

r = 6.5
