Answer:

The answer is C. 28.8 in

Step-by-step explanation:

Given a=16 and b=24,

c = 28.84441 = 8√13

∠α = 33.69° = 33°41'24" = 0.588 rad

∠β = 56.31° = 56°18'36" = 0.98279 rad

h = 13.3128

area = 192

perimeter = 68.84441

inradius = 5.57779

circumradius = 14.42221 = 4√13

My circumference is 20 cm what is my diameter and radius?
Musya8 [376]

Answer:

The diameter of the circle would be: 6.4 cm. rounded or 6.36619772 cm.

The radius of the circle would be: 3.2 cm. rounded or 3.18309886 cm.

Step-by-step explanation:

<h3>The diameter can be solved using: D = \frac{C}{\pi }</h3>

So, the first step would be : D = \frac{20}{\pi }

Then : D = 20 ÷ \pi

Finally, the answer will be : 6.36619772 cm. or 6.4 cm.

<h3>The Radius can be Solved using: r = \frac{c}{2\pi }</h3>

The first step would be : r = \frac{20}{2\pi }

Then : 20 ÷ 6.2831853071796 (2\pi)

Finally, the answer will be : 3.18309886 cm. or 3.2 cm.

Answer:

See answers below.

Step-by-step explanation:

For formula to find the volume of rectangular prism is given below:

Volume\:=\:whl

11. Putting the given values, we have:

200=\left(2\frac{1}{2}\right)\left(h\right)\left(8\right)\\\\h=10

12.\:\:Volume=\left(8\frac{1}{2}\right)\left(4\right)\left(11\right)\\\\Volume = 374

Write the expression as the sine, cosine, or tangent of an angle. cos 107° cos 42° + sin 107° sin 42°
7nadin3 [17]
Let a =107°   and b=42°;

So cos 107° cos 42° + sin 107° sin 42°  = cosa.cos42 + sina.sinb = cos(a-b)

and cos 107° cos 42° + sin 107° sin 42°  = cos(107-42) = cos(65°)
