Answer:
Number of sides are 12.
Step-by-step explanation:
Given that smallest angle of rotational symmetry for a regular polygon is 30°.
we have to find the number of sides does the regular polygon have.
If we can rotate a figure around a center point by fewer than 360° and the figure appears unchanged, then the figure has the rotation symmetry.
Now as at the centre the angle is 360 and all the angles at the centre formed equal i.e
Hence, 12 number of sides the polygon have.
Answer:
38.45
Step-by-step explanation:
Answer:
27 inches
Step-by-step explanation:
the formula for the circumference is 2 × pi × r
so: 2 × pi × r = 84.78
so 84.78/2pi = r
r = 13.5
we want the diameter which is 2 x r
so the diameter is 27
Answer:
Step-by-step explanation:
By my definition, no. There's a continuity up to and including just before 1 approaching from the left, and there's a continuity just after 1 going to the right. But 1 itself has a special definition h(x) = 4 when x = 1 and that makes it discontinuous.
