Central angle of a regular polygon:
Ф = 360° : n.
If n=12: Ф = 360° : 12 = 30°
At the angle of rotation Ф = 30° the image of the polygon will coincide with the preimage.
Answer:
22.1
Step-by-step explanation:
Because of it being a pyramid we must use the equation Bh1/2
B = L + W we assume that the base is a perfect square meaning all sides are the same length B = 4.8 + 4.8 = 9.6 then we multiply by the height
9.6 x 4.6 = 44.16 next you divide by 2 or multiply by .5
44.16/2 = 22.08 then finally rounding to the nearest tenth
making 22.1 cubic inches
The answer is 3/4ths. If you have any questions please ask
Area of one face =4/5 *4/5=16/25 (because the face is a square)
There are 6 such faces,
so the surface area = 6*(16/25)=96/25
if you need write that is a fraction 96/25,
if you need in decimal form,then 3.84
