# Thread: please help calculate the angle subtended

1. ## please help calculate the angle subtended

if the area of a sector of a circle is $2.88m^2$ an the radius is 1.73m,calculate the angle subtended at the center of the circle in radians and in degrees

$A = \frac{\pi r^2 \theta}{2\pi} = \frac{r^2 \theta}{2}$ if $\theta$ is measured in radians, or $A = \frac{\pi r^2 \theta}{360}$ if $\theta$ is measured in degrees.

Substitute your values and solve for $\theta$ in both cases.
