Question

In a circlr, if an arc of 5.5cm length subtends an angle of measure π/16 at the centre , then find the radius of the circle​

Answer 1

Answer:

Radius = 28 cm

Step-by-step explanation:

Length of arc = l = 5.5 cm

Angle subtended at the centre = θ = π/16

We know that

$θ = \frac{l}{r}$

So,

$r = \frac{l}{θ}$

So,

$r = \frac{5.5}{ \frac{\pi}{16} } = \frac{5.5 \times 16}{\pi}$

So,

$r = \frac{88}{ 3.14 } = 28 \: cm$
