How many faces does a dodecahedron have
A dodecahedron has 12 regular pentagonal faces, 20 vertices, and
30 edges. Three faces meet at each vertex.
The ratio of the lengths of corresponding parts in two similar solids is 21 What is the ratio of their surface areas
don't you mean 2:1 instead of 21. The answer is 4:1
4:1
Good luck with Apex :)
If the ratio between the radii of two spheres is 23 then what is the ratio of their volumes
Volume of a sphere of radius r: V = 4pi/3 x r3 If the ratio of the radii of two spheres is 23,
then the ratio of their volumes will be 233 = 1,2167
The ratio of surface areas of two similar solids is equal to the square root of the ratio between their corresponding edge lengths
What is the volume of a sphere with a radius of 12 units
The volume of a sphere with a radius of 12 units is: 7,238 units3
The answer above is correct but the answer ALSO can be 2304 units3
A right cylinder has a radius of 3 and a height of 12 What is its surface area
Total surface area is about 282.74 units2 (90 pi)
(Using pi = 3.14 gives the estimate 282.6)
SA = (pi 2r) x h + 2 (pi r2) = 72 pi + 2 (9 pi) = 90 pi
The ratio of the volumes of two similar solid polyhedra is equal to the square root of the ratio between their edges
What is the surface area of a sphere with a radius of 12 units
the formula for surface area of a sphere is 4pi(r squared)
so do
4x3.14x144
equals
576 pieunits^2
What is a solid consisting of a polygon a point not in the same plane as the polygon and all points between them
Which solid figure has a base that is a polygon and triangular faces that meet at a vertex
Which types of polygons are the faces of a dodecahedron
regular pentagons....
Kyah!
Which expression gives the volume of a sphere with radius 17
Which molecule is a stereoisomer of cis-2-pentene
Trans-2 pentene is a stereoisomer of cis-2-pentene.
How do you solve the Surface area of a regular pyramid
There is no "regular pyramid". There are triangle pyramids,
square pyramids, pentagon pyramids, etc.
With the information given in your question, there is no way to
answer.
What axis of the sphere below is 16 units in length What is the surface area of the sphere
The answer is given below.
What is the volume of the sphere shown below with a radius of 3
The two prisms below are similar. What is the value of x
The answer is 3--apex
The answer is 4--apex
These are the answers to 2 different apex with the same question but different numbers
Enjoy!
The two cones below are similar. What is the height of the smaller cone
The two solids below are similar and the ratio between the lengths of their edges is 35. What is the ratio of their surface areas
If the lengths are in the ratio 3:5, then the surface areas are
in the ratio 9:25.
If two cylinders are similar and the ratio between the lengths of their edges is 3 11what is the ratio of their volumes
What is the volume of the cylinder shown below with a heigh 7 and a radius of 12
Volume of cylinder: pi*12 squared *7 = 3166.725 cubic units
rounded to 3 decimal places
