We have to find,
The circumference of the given circle in terms of the π.
The formula we use,
→ C = 2πr
Then we can find the circumference,
→ 2 × π × r
→ 2 × π × 14
→ 28π in.
Hence, option (b) is correct answer.
Answer:
b. 28 in.
Step-by-step explanation:
circumference of a circle = 2 r
whrere r is the radius of rhe circle
= 2 × × 14 in.
<u>= 28 in. </u>
that is option b
7 to the second power... because 7 times is 49 and 49-49 is 0... so 7 to the second power
5 mins
680/4
=170 meters (quarter of 680m)
170/34
=5 mins
problem 4
Velocity is +2.0m/s and constant acceleration is -0.5m/s^2
For every second the velocity drop by 0.5 m/s, so after 2 seconds the velocity is 1 m/s.
problem 5
Accelerate from rest to 28m/s means go from 0 to 28m/s so with
a constant acceleration of 5.5 m/s^2 it will take 5.09 second
Probability of event E = (4/10) = 0.40
Note that n(E) is the number of outcomes in E
n(S) is the number of outcomes in S
And with each outcome having equal likelihood of occurring,
SetS = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}.
n(S) = 10
Event E = {1, 4, 7, 9}.
n(E) = 4
Probability of event E = n(E)/n(S)
Hope this Helps!!
