Find the three trigonometric..pls help due very soon
astraxan [27]

Answer:

sin 0 = 24/25

cos 0 = 7/25

tan 0 = 24/7

Step-by-step explanation:

hey there!

sine = opposite divided by hypotenuse

the opposite of angle 0 is 24 and the hypotenuse is 25 so sin 0 = 24/25

cosine = adjacent divided by hypotenuse

the adjacent of 0 is 7 and the hypotenuse is 25 so cos 0 = 7/25

Tangent.= opposite divided by adjacent

the opposite of 0 is 24 and the hypotenuse is 7 so tan 0 = 24/7

HELPPPP!!! please!!!

By looking at the graph, we can see that the shape is a quarter of a circle.

The area of a circle is:

a =  \frac{1}{2} \pi {r}^{2}

So, this "quarter circle" is:

a =  \frac{1}{4}  \times  \frac{1}{2} \pi {r}^{2}

R is the radius (the diagram shows the radius is 8), so we can now find the area:

a =  \frac{1}{4}  \times  \frac{1}{2} \pi  \times {8}^{2}  \\ a =  \frac{1}{8} \pi \times 64 \\  \\ a =  \frac{64\pi}{8}  \\ a = 8\pi

The area is 8π.

Joseph made a model rocket by attaching a cone
Lerok [7]

Answer:

Area = 270π inches squared. Volume = 550π inches cubed

Step-by-step explanation:

Surface Area:

Cylinder Area=2πrh+2πr^2= 180π+50π=230π inches squared.

Cone Area = πr(r+√(h^2+r^2)) = 5π(18) = 90π inches squared.

Total Area = 230π+90π = 320π inches squared.

Total Area - base = 320π-50π = 270π inches squared.

Volume:

Cylinder volume = πr^2h = 450π inches cubed

Cone volume = πr^2(h/3) = 100π inches cubed

Total Volume = 550π inches cubed
