Question

It says to calculate the area of the sector and t round to the nearest hundredth and to use 3.14 for Pi

Answer 1

Answer:

Step-by-step explanation:

The formula for the area of a sector is

$A=\frac{\theta}{360}*\pi r^2$ where theta is the measure of the central angle (which is the same measure as that of the arc that is intercepted by the 2 radii formig the angle), and r is the radius.

For us, theta is 90 degrees and r is 20. Filling in the formula:

$A=\frac{90}{360}*(3.14)(20)^2$ which simplifies down a bit to

$A=\frac{1256}{4}$ so

A = 314 m squared
