Step-by-step explanation:
let an amount be a
increase an amount by 10% and then by 30%
= a*1.1 *1.3 = a*1.43
Given:
Area of a circle, A=50.265 sq. units.
Radius of circle, r = 4 units.
To find:
The value of π to the nearest thousandth.
Solution:
Formula for area of a circle is



Now, using
expression, we can find the value of π.




Approximate the value to the nearest thousandth (three digits after decimal).

Therefore, the approximated value of π is 3.142.
13.42 is how long the wire is to the nearest hundredth of a foot

Answer:
7 sqrt(3) =x
Step-by-step explanation:
We know that sin 60 = opposite / hypotenuse
sin 60 = x/14
Multiply both sides by 14
14 sin 60 = x
14 * (sqrt(3)/2) =x
7 sqrt(3) =x
