57°

noname [10]

Answer:

c = 29

Step-by-step explanation:

Law of sines is given as: $\frac{a}{sin(A)} = \frac{b}{sin(B)} = \frac{c}{sin(C)}$

B = 180 - (57 + 44) = 79°

b = 41

C = 44°

c = ?

Thus:

$\frac{b}{sin(B)} = \frac{c}{sin(C)}$

Substitute

$\frac{41}{sin(79)} = \frac{c}{sin(44)}$

Multiply both sides by sin 44

$\frac{41}{sin(79)}*sin(44) = \frac{c}{sin(44)}*sin(44)$

$\frac{41*sin(44)}{sin(79)}*sin(44) = c$

c = 29.0140633 ≈ 29

A circle with radius 3 has a sector with a central angle of 1/9 pi radians

marissa [1.9K]

Complete question:

A circle with radius 3 has a sector with a central angle of 1/9 pi radians

what is the area of the sector?

Answer:

The area of the sector = $\frac{\pi}{2}$ square units

Step-by-step explanation:

To find the area of the sector of a circle, let's use the formula:

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

Where, A = area

r = radius = 3

$\theta = \frac{1}{9}\pi$

Substituting values in the formula, we have:

$A = \frac{1}{2}*3^2* \frac{1}{9}\pi$

$A = \frac{1}{2}*9* \frac{1}{9}\pi$

$A = 4.5 * \frac{1}{9}\pi$

$A = \frac{\pi}{2}$

The area of the sector = $\frac{\pi}{2}$ square units
