Answer
Find out the area of the running track that goes around the field .
To proof
Formula
Area of rectangle = length× breadth
area of running track = outside area - inside area
First case ( outside )
length = 73 + 2 × 9.76
= 92.52m
Breadth = 84.39 m
radius of outside semi circle
=46.26m
outside area = area of rectangle + 2× area of the semi- circle
= 92.52× 84.39 + 3.14× 46.26 ×46.26
= 7807.76+ 6719.56
= 14527.32 m² ( approx)
Second case
radius of the semi- circle
=36.5m
inside area = area of rectangle + 2× area of the semi- circle
= 73× 84.39 + 3.14× 36.5 ×36.5
= 6160.47 + 4183.27
= 10343.74m²
area of running track= 14527.32 m² - 10343.74m²
= 4183.58m²
Hence proved
Answer:
O C. x = 3
Step-by-step explanation:
If a line is parallel to y-axis, the equation of the line is x = constant because it is at a constant distance from y-axis. so for the given question, x = 3 is the equation of the line passing through (3,2).
The answer is 6 but it crossed on the X axis
Next time, please separate the expressions with a comma, semicolon or the word "and."
I need to assume that you meant "8/(8a^2)" If that's the case, then what you have here is
1 8
--- and -----------
a 8a^2
I would then cancel the 8s, obtaining:
1 1
--- and -----------
a a^2
a
and then multiply 1/a by (a/a): -----------
a^2
to obtain
a 1
------- and -------
a^2 a^2
There is only one LCD here, and it's "a^2."
