Its a true equation. Every value of x would make it true. Every number is real (XER)
The surface area of a sphere is A = 4 π R² .
Sadly, the question doesn't give you 'R', so you have to
back it out of the circumference.
Circumference = π (diameter)
Divide each side by π : Diameter = circumference / π
Radius = 1/2 diameter: Radius = circumference / (2 π)
Area = 4 π R² =
4 π (circumference/2π)² =
4 π (circumference)² / 4 π²
Divide top and bottom by 4π : Area = (Circumference)² / π
Circumference = 37.68 units
Area = (37.68)² square units /π =
<em>451.93 square units</em>
Answer:
C
Step-by-step explanation:
over the interval [-1,1], f(x) is greater than 0
Answer:
16
Step-by-step explanation:
you would get c alone so you subtract 5 to the other side
