<h3>The answer for the above mentioned problem is JL = 12.5
Step by step explanation:
Given:
JM = 8
KM = 6
To Find:
JL = ?
Formula to be used:
= JM x ML
In order to find " JL" we must first find "ML",
= JM x ML
= 8 x ML
36 = 8 x ML
36/8 = ML
ML = 4.5
Now JL = 4.5+8
= 12.5
Thus the value of JL = 12.5
Answer:
76.4 m
Step-by-step explanation:
The race track has two straights and two semi circles.
Each straight is 80m
total perimeter for the straights is 80 * 2 = 160m
two semi circles which creates a full circle
perimeter of a full circle = d
NB : (d) is the diameter
therefore we can find the value of the diameter
400 = 160 + d
400- 160 = d
240 = d
d = 240/
d = 76.394.....
<u>d = 76.4 m</u>
