This is the answer in expanded form: 100,000 + 10,000 + 4,000 + 6<span />
<span>Circumference of a circle = 2 π r
(where r is the radius)
Area of a circle = π r^2
(where r is the radius)
you have to find the radius
C = 2π unit
r = 1 unit
Area = π square units

Answer:
6 units squared
Step-by-step explanation:
Formula:
area = 0.25 * √( (a + b + c) * (-a + b + c) * (a - b + c) * (a + b - c) )
Assign variables:
A = 5, B = 4, C = 3.
Distribute:
area = 0.25 * √( (5 + 4 + 3) * (-5 + 4 + 3) * (5 - 4 + 3) * (5 + 4 - 3) )
Combine like terms
area = 0.25 * √( (12) * (2) * (4) * (6) )
Multiply:
area = 0.25 * √(576)
Square root:
area = 0.25 * 24
Multiply:
area = 6 units squared
