I didn't know what the circumcenter is, so I went and looked it up.
In the process, I accidentally learned something.   Thank you.

The circumcenter of a right triangle is the point where
the perpendicular bisectors of all three sides meet.

For the triangle on your screen, that point is the mid-point of the
hypotenuse.  It looks like   (-5/2, -2).

I attached my drawing to this answer.
Please have a look.

Need to find the volume of these composite figures. Thank You!​
Natali [406]

Answer:

<h2><em><u>3. V = 1,498.2</u></em></h2><h2 /><h2><em><u>4. V = 2,813.44</u></em></h2><h2 /><h2><em><u>5. V = 96.293</u></em></h2>

Step-by-step explanation:

3. Formula of a Cylinder + Formula of a Cone = Total

V=πr^2h + V=πr^2h

/3 = total

V = 3.14 * 36 * 10 + V = 3.14 * 36 * 10/3

V = 1,130.4 + V = 376.8 = Total

<h2><em><u>V = 1,498.2</u></em></h2>

4. Formula of Cone + Formula of Cone = Total

V=πr^2h

/3 + V=πr^2h

/3 = Total

V = 3.14 * 36 * 8/3 + V = 3.14 * 100 * 8 = Total

V = 301.44 + 2,512 = Total

<h2><em><u>V = 2,813.44</u></em></h2>

5. Formula of a cylinder + formula of a sphere = Total

V=πr^2h + V=4

/3πr^3 = Total

V = 3.14 * 4 * 5 + V = 4/3 * 3.14 * 8

V = 62.8 + V = 33.493 = Total

<h2><em><u>V = 96.293</u></em></h2>

DEFINITELY hope this helped,
