we are given
exterior angle is 18
so,

now, we can use formula
number of sides of regular polygon = 360/(exterior angle)
so, we get


so, number sides is 20..........Answer
Answer:
The square root of 120 is about 10.95
Step-by-step explanation:
Well to find the area of a circle Pie times r^2. But If you already have the diameter, you could either split the diameter in half, and do the regulaur formula, OR you could ude this formula ----> Pie times The diameter
√m/3 = 4
To remove the radical sign, square both sides.
(√m/3)² = 4²
m/3 = 16
To remove the denominator of 3, multiply both sides by 3.
3 (m/3) = 3(16)
m = 48
To check: Substitute m by its value.
√m/3 = 4
√48/3 = 4
√16 = 4
4 = 4
