I tried I hope this helps in any kind of way
A track has the shapes shown. what is the perimeter ?
1 answer:
Break this problem down first. You have two lines each with length of 5. You also have two halves of a circle, combine them to get a full circle with a radius of 2. The formula to find the perimeter of a circle is
and this gives a perimeter of 12.566 for the circle. Add this to your sides and you get a total of 22.566 which is answer B

Step-by-step explanation:
Question 8
Let the equation of a line passing through two points and
is given by,
y = mx + b
Here, m = slope and y-intercept = b
Since, m =
For two points (1, 4) and (5, 8),
m =
m = 1
Equation will be,
y = (1)x + b
y = x + b
Since, this line passes through (1, 4),
4 = 1 + b
b = 3
Therefore, equation of the line will be,
y = x + 3
Question 9
Let the equation is y = mx + b
m =
For two points (2, 10) and (6, 4)
m =
m =
By substituting the value of 'm' in the equation,
y =
Since, this line passes through (2, 10)
10 =
b = 10 + 2
b = 12
Therefore, equation of the line will be,
