Answer:
Step-by-step explanation:
-9x^3(x^2 - 4x - 21) =
-9x(x - 7)(x + 3) <===
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:
Therefore the Answer would be (D) 73
Step-by-step explanation:
Let A = 65 feet and B = 33 feet.
Let C represent teh length of the hypotenuse, the length of the wire.
We use the Pythagroem Therom to find C.
