Hello!
A semicircle's perimeter can be found using the formula:
We can plug in the values to solve for the perimeter.
<h3>Solve</h3>In terms of Pi, it is ,
Exact value of Pi, it is 15.42477
Approximation of Pi (3.14), it is = 15.42
First graph it
#1
Maximum height is the y coordinate of vertex
- (2,144)
Max height
- 144m
#2
Time is the x coordinate of vertex
- 2s
#3
- y is 0
x intercepts are the solutions
- (-1,0)U(5,0)
Take it positive
- t=5s
#4
put in function
- y=-16(1)+64+80=-16+144=128ft
