Area = 12.00

Step-by-step explanation:

Given

$\theta = m\angle RST = 86^o$

r = RS = 4

Required

Area of RST

The sector area is calculated using:

$Area = \frac{\theta}{360} * \pi r^2$

So, we have:

$Area = \frac{86}{360} * 3.14 *4^2$

$Area = \frac{86* 3.14 *4^2}{360}$

$Area = \frac{4320.64}{360}$

Area = 12.00 ------------ approximated
