The formula to get the circumference is 2πr, π being pi and r being your radius.
Your r is 0.9 since the radius is half the diameter.
2πr = 2 x 3.142 x 0.9
= 5.6556cm
≈ 5.7cm
(y - 6) 2 = 9
(y + 6) 2 = 9
Answer: The correct option is
(B)
Step-by-step explanation: We are given to select the equation that is formed when completing the square on the following equation :
We will be using the following formula :
From equation (i), we have
Thus, the required equation that is formed is
Option (B) is CORRECT.
(a) F = ma , a = F/m
(b) a = F/m, a= -25/10 = -2.5 units
(c)m = F/a, m= 25/5 = 5 units
