Question

In a circle, an angle measuring pie over 2 radians intercepts an arc of length 1 pie. Find the

Answer 1

Answer:

2 units

Step-by-step explanation:

We are given that

Angle ,$\theta=\frac{\pi}{2}$radian

Length of an arc=$\pi$

We have to find the radius of circle in simples form.

We know that

$\theta=\frac{l}{r}$

Where l=Length of arc

r=Radius of circle

Using the formula

$\frac{\pi}{2}=\frac{\pi}{r}$

$r=\frac{2\times \pi}{\pi}$

$r=2$units

Hence, the radius of the circle=2 units
