Answer: radius = 6.5millimeters; Area = 132.7m²
Step-by-step explanation:
The circumference of a circle = 2πr
The area of a circle = πr²
The circumference of a button is 40.8 millimeters. Then we can get the radius, thus will be:
Circumference = 2πr
40.8 = 2 × 3.14 × r
40.8 = 6.28r
r = 40.8/6.28
r = 6.5
Radius is 6.5 millimeters
Area = πr²
Area = 3.14 × 6.5 × 6.5
Area = 132.7m²
There is two hundred and four (204) on a standard chessboard.
Answer:Add 4.3x to both sides of the equation.
Step-by-step explanation:
The given equation is expressed as
3.7x - 18 = - 4.3x - 34
The main aim is to solve for x and x is on the left hand side and the right hand side of the equation. So the most efficient step would be to make all the terms containing x to be on the left hand side of the equation and the constants to be on the right hand side of the equation.
Therefore, the most efficient first step to solve for x in the equation would be
Add 4.3x to both sides of the equation.
I hope this helps you
