A cone has a 4 radius and a 8 height what is the volume
Marta_Voda [28]

Hey there! I'm happy to help!

To find the volume of a cone, you multiply the base by the height and then divide by three.

First, we need to find the base. A cone has a circle for the base. To find the area of a circle, we square the radius and multiply it by pi (we will use 3.14).

4²=16

16×3.14= 50.24

Now, we multiply our base by the height.

50.24×8=401.92

Finally, we divide by three.

401.92÷3≈133.973 (to nearest thousandth)

Therefore, the volume of the cone is about 133.973 units cubed. If you were to use exact pi, it would be more like 134 because of all those decimals after pi!

Now you can find the volume of cones!

I hope that this helps! Have a wonderful day!

Right triangle ABC has three sides with lengths AB= 119, BC = 169, CA= 120. Find the value of cos C. hint: draw and label the tr
GenaCL600 [577]

Answer:

\cos(C)=\frac{120}{169}

Step-by-step explanation:

The triangle is shown in the attachment.

Recall that;

\cos(C)=\frac{Adjacent}{Hypotenuse}

This implies that;

\cos(C)=\frac{|AC|}{|BC|}

We substitute the values into the ratio to obtain

\cos(C)=\frac{120}{169}
