Find the radius of a circle with circumference of 45.84 meters. use 3.14

approx. 7.3 m

Step-by-step explanation:

The formula for the circumference of a circle is  s = r·Ф, where r is the radius and Ф is the central angle in radians.

Here C = 45.84 m = 2π·r.  Solving for the radius, r, we get:

       45.84 m

r = = 7.299 m, or approx. 7.3 m.

          2(3.14)

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)
