Answer: Ok So If you know the diameter or radius of a circle, you can work out the circumference. To begin with, remember that pi is an irrational number written with the symbol π. π is roughly equal to 3.14.
The formula for working out the circumference of a circle is:
Circumference of circle = π x Diameter of circle
This is typically written as C = πd. This tells us that the circumference of the circle is three “and a bit” times as long as the diameter."
Step-by-step explanation:
The 3 digits in the unit period is 817
12x - 4x = 8 + 3 - 3
8x = 8
X = 1
260 minutes. 4 times 60 = 240 + 20 minutes i s the quarter
The missing side would be B = 15
