Step-by-step explanation:

$\cos(a) + 2 \cos(a + 240)$

$\cos(a) + 2 \cos(a) \cos(240) - \sin(a) \sin(240)$

$\cos(a) + 2( - \frac{ \cos(a) }{2} + \frac{ \sqrt{3} }{2} \sin(a) )$

$\cos(a) - \cos(a) + \sqrt{3} \sin(a)$

$\sqrt{3} \sin(a)$

If you graph the new identity, and the og identiy, they will be conciding graphs, so they are the same identity.

Answer:

688.7

Step-by-step explanation:

Top and Bottom

Area = 3/4 * pi * r^2

r = 6

Area = 3/4 * 3.14 * 6^2

Area = 84.78

Don't round yet.

Vertical surface

Vertical surface = 3/4 * pi * d * h

d = 12 inches (the diameter)

Vertical surface = 3/4 * 3.14 * 12 * 15

Vertical surface = 423.9

Two inner faces

They are both rectangles

Area = 2 * L * W

L = 15

w=6

Area = 2 * 15 * 6 <u> 180</u>

Total 688.68

Total = 688.7
