Answer:
x = 135
Step-by-step explanation:
Use the right triangle altitude theorem and similar triangles.
x/81 = 225/x
x^2 = 81 * 225
x = 9 * 15
x = 135
Answer:
can you plz rewrite the question I want to help but I can't see it. you can even take a picture of the question.
b) By capacity, the problem asks the volume. So let's find the volume of that small cylinder
So by plugging into the formula the given data we can tell that the capacity of that cylinder is indeed 808.5cm³
c) Note that now, the point is to find the Volume of that cuboid (rectangular prism), which we can find by doing the following formula:
d) And finally, the density is given by the following ratio:
15 mph = 15 miles traveled in a one hour time span.
15+3=18 miles, 60 minutes- 30 minutes = 30 minutes.
18 miles in the span of 30 minutes
By definition we have:
A triangular pyramid (also called tetrahedron) is a polyhedron whose surface is formed by a base that is a triangle and triangular lateral faces that converge in a vertex that is called apex (or apex of the pyramid).
It will be composed, therefore, by 4 faces, the triangular base and three lateral triangles that converge at the vertex.
Thus, the surface area is:
As = 4 * (50.5) = 202 in ^ 2
Answer:
The total surface area of the triangular pyramid is:
202 in ^ 2
