Step-by-step explanation:
Btw The one on the upper right hand side is Right angle
The value of x is 3.8
<em><u>Solution:</u></em>
<em><u>Given equation is:</u></em>
![x + 7.4 = 11.2](https://tex.z-dn.net/?f=x%20%2B%207.4%20%3D%2011.2)
We have to solve the equation for "x"
Move the terms so that you end up with only terms involving x on one side of the sign and all the numbers on the other
Therefore, we get
x + 7.4 = 11.2
When we move 7.4 from left side to right side of equation it becomes -7.4
x = 11.2 - 7.4
Subtract 7.4 from 11.2
x = 3.8
Thus value of x is 3.8
The equation for the area of a circle is A = pi times r^2
The radius is half the diameter, making it 5.
A = pi times 5^2
Simplify to: A = pi times 25
A = 78.5
