45-45-90 isosceles right triangle
x=y
x^2+y^2=12^
x^2+x^2=12^2
2x^2=12^2
x^2=12^2/2
x=12/square root of 2
x=12.square root of 2/2
x=6.square root of 2
Answer:1250 units
Step-by-step explanation:
circumference=7850
Radius=?
Radius=circumference ➗ (2xπ)
Radius=7850 ➗ (2 x 3.14)
Radius=7850 ➗ (6.28)
Radius=1250 units
The formula is : 3.14 times r(radius)^2
Scientific notation is writing numbers as a product of a power of 10 to shorten them.
