Answer:
8
Step-by-step explanation:
Recall these two equations for circumference and diameter.
Circumference = 2*pi*radius
Diameter = radius*2
25.12 = 2*pi*radius
Radius = 4
Diameter = 4*2 => 8
Thus the diameter is 8
Answer:
6 feet
Step-by-step explanation:
Let x represent the length of "another side." Then "one side" is ...
2x -10 . . . . . . 10 feet shorter than twice another side
The sum of these two side lengths is half the perimeter, so is ...
x + (2x -10) = 14 . . . . . two sides are half the perimeter
3x = 24 . . . . . . . . . . . . add 10, collect terms
x = 8 . . . . . . . . . . . . . . .divide by the coefficient of x
(2x -10) = 2·8 -10 = 6 . . . . find "one side"
We have found "one side" to be 6 feet long, and "another side" to be 8 feet long. The shorter side is 6 feet.
X= any coordinate on the x-axis . but I'm confused about the " f "
3²×7................................................
The answer is: "
40 cm " .
_________________________________________________________<u>Note</u>:_________________________________________________________ ;
Solve for "x" (in "cm" ) ;
→ 5x = 200 * 1 ;
→ 5x = 200 ;
Divide each side of the equation by "5" ;
to isolate "x" on one side of the equation; & to solve for "x" ;
→ 5x / 5 = 200 / 5 ;
to get:
→ x = 40 .

40 cm " .
