Question

Find the length $s$and area $A$. Round answers to three decimal places.

Short answer

The solution is $s\approx 14.661$yard and$A\approx 87.965$square yard .

Step-by-step solution

Step 1. Given information 

Step 2. Calculation 

Here the length is -

$s=r\theta$

$=12\times 70\times \frac{\mathrm{\pi }}{180}$

$\approx 14.661$

Now the area is -

$A=\frac{1}{2}{r}^2\theta$

$=\frac{1}{2}\times {\left(12\right)}^2\times 70\times \frac{\mathrm{\pi }}{180}$

$\approx 87.965$

Therefore, length $s$is $14.661$yard and the area $A$is $87.965$ square yard .
