Answer:
C. 18°
Step-by-step explanation:
The <em>order of symmetry</em> (n) is the number of times a shape fits onto itself during a complete turn through 360°.
The <em>angle of rotational symmetry</em> (θ) is the smallest angle through which the shape must be rotated to coincide with itself.
To find the angle, y<em>ou divide the number of degrees in a circle by the order of symmetry</em>.
θ = 360/n
= 360/20
= 18°
Answer:
the change in height is 1/100 mile
Step-by-step explanation:
1/50 is also equal to 2/100, and since the previous height was 3/100 then you can just subtract 2/100 from 3/100 to get 1/100
Answer:
r = 
Step-by-step explanation:
Given
A = 4πr² ( divide both sides by 4π )
= r² ( take the square root of both sides )
= r
