Question:
1. 3(x-2)+2=2(x-4)
2. Find the area of a circular flower bed whose diameter is 6 meters.
Use pie=3.14 as an approximate value.
Answers:
1.
3(x-2)+2=2(x-4)
==> 3*x - 3 * 2 + 2 = 2 * x - 2 * 4
==> 3x - 6 + 2 = 2x - 8
==> 3x - 4 = 2x - 8
subtract 2x from both sides......
==> 3x - 4 - 2x = 2x - 8 - 2x
==> 3x - 2x - 4 = 2x - 2x - 8
==> x - 4 = -8
Add 4 on both sides....
==> x - 4 + 4 = -8 + 4
==> x = - 4. which is the required solution.
2. Find the area of a circular flower bed whose diameter is 6 meters.
Use pie=3.14 as an approximate value.
Area of a circle whose radius is 'r ' is given by the formula,
So here the area of the flower bed is given by,
Given, diameter = 6 meters.
==> radius = 3 meters.
So
==> 3.14 * 9
==> 28.26 meters.
Hope you found the explanation useful.
