Y=1x-10 (sorry I could be wrong)
Answer:
9π ft² or approximately 28.26 ft²
Step-by-step explanation:
The area of a circle is A=πr².
Plug 3 in for the radius.
A=π(3²)
A=9π ft²,
or using 3.14 for pi,
Approximately 28.26 ft².
Answer:
(i)
time to bounce in one direction is 0.75 sec
(ii)
time to bounce in other direction is 1.5 sec
(iii)
total time is 2.25 sec
Step-by-step explanation:
Time to bounce in one direction:
we can see that height is increasing till t=0.75sec
so, time to bounce in one direction is 0.75 sec
Time to bound in other direction:
we can see that height is decreasing from t=0.75 to 2=2.25 sec
so, time to bounce in other direction is 2.25-0.75
=1.5 sec
Total time :
We know that
total time = (time to bounce in one direction)+(time to bounce in other direction)
now, we can plug values
total time =0.75+1.5=2.25 sec
I think you need to figure out how much he makes an hour first then its very easy from there.
