Answer:
Step-by-step explanation:
The area of a circle is given by :
Where
r is the radius of the circle.
If we talk about the area of half of the circle, it means we have to half the area such that,
Hence, this is the required solution.
Well, "circumference" is a word that's reserved for circles. If you want
the distance all the way around a rhombus, that's called the "perimeter"
of the rhombus.
To find it, you need to know the length of one side. Then, since a rhombus
has 4 sides and they're all the same length, you just multiply the length you
have by 4 .
The equation to get the circumference of a circle is: (C = circumference & r = radius)
C = pi times diameter
The information given:
Radius = 84 inches
What you can get from the information given:
Diameter = 168 inches
So:
C = pi times diameter (168 inches)
C = pi times 168 inches (which is 527.52 inches)
C = 527.52

Dividing any number by 0.25 is the same as multiplying by 4, as 0.25/1.00 = 1/4.
Your equation would be (in simpler terms)
56.3 x 4.
56.3 x 4 is 225.2
Your answer is 225.2
Hope this helps :)
