Answer:

$595.54$

Step-by-step explanation:

The formula for a sector of a circle with angle $\theta$ is $\frac{\theta}{360}\cdot r^2\pi$ .

Substituting given values, we have:

$\frac{141}{360}\cdot 22^2\pi\approx \boxed{595.54}$

Answer:

14.285714285714 %

Step-by-step explanation:

suppose the weekly payment is of x dollars

Then

Previous payment : $(x/40) per hour

New payment : $(x/35) per hour

Then

The percentage increase in the hourly rate of pay is :

$=\frac{\frac{x}{35} -\frac{x}{40} }{\frac{x}{40} } \times100$

$=\frac{\frac{5x}{1400} }{\frac{x}{40} } \times100$

$=\frac{5x}{1400} \times \frac{40}{x} \times100$

$=\frac{200}{1400} \times100$

$=\frac{1}{7} \times100$

$=14.285714285714$
