14 hours or 2 hours. Im not sure
C = 2πr Divide both sides by 2π
C/2π = r Switch the sides to make it easier to read
r = c / 2π
Answer:
Yes!
Step-by-step explanation:
Answer:
-2
Step-by-step explanation:
Slope = (4-8) / (9-7) = -4/2 = -2
Answer: area for circle is πr² so πr² =28.26 and we can sub 3.14 as pi
3.14*r²=28.26 we can divide by 3.14 to get r² on it's own
r²=28.26/3.14
then we root both sides to get r on it's own
28.26/3.14=9 √9=3
and the diameter is double the radius 3*2=6 so the diameter is 6
