Find the area of a sector with a central angle of 120° and a diameter of 7.3 cm. Round to the nearest tenth.

Andru [333]

Answer: $14cm^{2}$

Step-by-step explanation:

diameter=7.3cm

radius= $\frac{diameter}{2}$

= $\frac{7.3}{2}$

=3.65cm

angle =120°

area= $\frac{angle (tita)}{360}$ × $\frac{\pi r^{2} }{1}$

= $\frac{120}{360}$ × $\frac{22}{7}$ × $3.65^{2}$

= $13.95cm^{2}$

≅ $14cm^{2}$

Answer:

The sum of all the possible values for z that satisfy the above equation is -5.

Step-by-step explanation:

The given equation is

$\frac{5}{z}-\frac{2z+4}{z+2}=-3$

We need to find the sum of all the possible values for z that satisfy the above equation.

The given equation can be rewritten as

$\frac{5}{z}-\frac{2(z+2)}{z+2}=-3$

Cancel out common factors.

$\frac{5}{z}-2=-3$

Add 2 on both sides.

$\frac{5}{z}-2+2=-3+2$

$\frac{5}{z}=-1$

$5=-z$

Multiply both sides by -1.

$-5=z$

Only z=-5 satisfy the given equation.

Therefore the sum of all the possible values for z that satisfy the above equation is -5.
