Answer:
8
Step-by-step explanation:i got it wrong to see what the answer was :)
If you divide the circumference C over the radius r, you get 2pi
2pi = C/r
this is because
C = 2pi*r
is one formula to find the circumference. Another formula is
C = pi*d
which works because d = 2r, ie the diameter is twice the radius.
Answer:
50 + 25 + (8*5) - (7 + 4)
Step-by-step explanation:
50 + 25 + (8*5) - 7 + 4 = 50 + 25 + 40 - 7 + 4
= 115 - 7 + 4
= 108 + 4
= 112
Yes. All even numbers are divisible by 2. Every single one of them
We know that the ratio is;

The angles in a triangle add up to give 180°
We can think of there being twelve "parts" that add up to 180°

So our ratio is;

So the smallest angle is 30°
