The answer is the second one because you 0.80 x 600=480 and 0.20 x 360=72 and then subtaract the 2 answers from each other and it will become 408
Answer:
1.125 m
Step-by-step explanation:
Given:
Initial height of the ball, 
Height after first bounce, 
Height after second bounce, 
So, the reduction in height after each bounce is half of the previous one. Thus, it follows a geometric sequence with the first term as 72 and common ratio of 
.
Therefore, the nth term of a geometric sequence is given as:
Here, 
. This gives,
.
Therefore, the height of the ball after sixth bounce is 1.125 m.
Answer:
1) Area:
So to find area follow the formula
a=πr^2
a=area
π= pi or 3.14 in this situation
r= radius
So we have only the diameter.
To in Find the radius you can divide the diameter by 2 and get the radius which is
84/2=42
3.14*42^2=
Area: 5538.96 ft^2
2) Circumference:
To find the circumfeence you just multiply the diameter by π or in this case 3.14.
c=πd
c= circumference
d= diameters
3.14*84=
Circumfrence: 263.76 ft
