If the area of a circle is 58 square feet, find the circumference. A. 22.35 ft. B. 26.99 ft. C. 4.25 ft. D. 42.5 ft.
Fed [463]

Answer:

  B.  26.99 ft.

Step-by-step explanation:

The formulas for circumference (C) and area (A) are ...

  A = πr²

  C = 2πr

Solving the area formula for r, we get ...

  r = √(A/π)

Substituting this into the circumference formula gives ...

  C = 2π√(A/π) = 2√(πA)

For the given circle, the numbers are ...

  C = 2√(3.14×58 ft²) ≈ 26.99 ft

HELP!<br> What is the solution to this system of equations?
goblinko [34]
5x - 3y + z = -6
x + 3y - z = 0
-------------------add
6x = -6
x = -1 <===

x + 3y - z = 0
4x + y + z = 7
------------------add
5x + 4y = 7

5(-1) + 4y = 7
-5 + 4y = 7
4y = 7 + 5
4y = 12
y = 12/4
y = 3 <===

5x - 3y + z = -6
5(-1) - 3(3) + z = -6
-5 - 9 + z = -6
-14 + z = -6
z = -6 + 14
z = 8 <===
