The formula for the area of a triangle is:
where B is the base of the triangle and h is the height
It appears that the height of the triangle is 5 units (not quite 4.5) and the base is 10 units.
Multiply these to get 50, and divide by 2 to get 25.
The area of the triangle should be 25 u²
Hope this helps! :)

Answer:
Step-by-step explanation:
Inicially we have to separate the sphere into 3 parts:
The donut + 1 ball cap (or a dome) + the cylinder hole = the Hemisphere
<em>vide picture</em>
As it shows in the picture we have to find the donut.
The donut = the Hemisphere - ( 1 dome + the cylinder hole)
- The hemisphere =
(from the hemisphere formula)
- 1 dome* =
- cylinder hole =
(h: cylinder height)
By basic algebra we have
D = 5.304
*The dome in the 1st picture is represented by the color orange.Looking into the second picture, the dome formula derivatives from the volume of a dome of a hemisphere. By using the following linear system:
- triangle_side2 + a2 = r2
- h + triangle_side = r
