Question

In circle S with mZRST = 86 and RS = 4 units find area of sector RST. Round to

Answer 1

Answer:

$Area = 12.00$

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
