blsea [12.9K]

Answer:

1. diameter=8 kilometres

2. area=98.96 inches

3. 37m

Step-by-step explanation:

1. diameter= 2*radius

2. area of sector=θ out of 360*π $r^{2}$ where θ is the angle

3. area of garden=π $r^{2}$

706.5=π $r^{2}$

$r^{2}$ =706.5/π

= 225(nearest whole)

r= $\sqrt{225}$ =15m

we now use Pythagoras theorem to find length of each pathway

$40^{2} =15^{2} +x^{2}$

1600=225+ $x^{2}$

$x^{2}$ =1600-225=1375

x= $\sqrt{1375}$ =37 m (to nearest whole)

ra1l [238]

Answer:

f(x) = $x^{3} - x^{2} - 10x -8$

Step-by-step explanation:

All you have to do is multiply (x + 1)(x + 2)(x - 4)

You should get $x^{3} - x^{2} - 10x -8$

So, f(x) = $x^{3} - x^{2} - 10x -8$
