The 'seconds' hand on the watch goes all the way around in 1 minute. <span>15 seconds is 1/4 of a complete 1-minute revolution. </span>So, the 2 cm is 1/4 of the way around the circle that the tip makes. This makes the full circumference of the circle 8cm.
<span>The length of the second hand will be the radius of the circle. Use the following equation: </span>
2 pi radius = circumference
Since we know the circumference, plug that in, and solve for the radius:
2 pi radius = 8 cm
radius = 8cm / 2 pi =<span> 1.27 cm</span>
I think the answer is c because Bill is surveying every fourth person who enters the mall, which would be the population surveyed. Hope I helped! (Let me know if I got it wrong)
Answer:
(2.9x10^8) divided by (9.2x10^6) will be equal to 31.52
Step-by-step explanation:
Given that:
(2.9x10^8) divided by (9.2x10^6)
we can write it as:
=2.9/9.2 * (10^8-6) (subtracting exponents of same bases in division)
=0.3152 * 10^2 (As 10^2 equals 100)
=31.52 (Answer)
I hope it will help you!
