Step-by-step explanation:
Divide by 23
Extract the square root.
Answer:
A = 90.25 pi in^2
Step-by-step explanation:
The circumference is given by
C = 2*pi*r
19pi = 2*pi*r
Divide each side by 2 pi
19pi / 2 pi = 2*pi*r/ 2pi
9.5 = r
The area is given by
A = pi r^2
A = pi ( 9.5)^2
A = 90.25 pi in^2
I assume what you want ti find is the value of m?
You try to have an quation of the form "m=" where on the one side there is nothing but m.
so first, let's get rid of the bracket:
-2(4-m)=10
-8+2m=10
now, let's add 8 to both sides:
-8+8+2m=10+8
2m=18
and divide by 2:
m=9
and that's our solution
Answer:
55-276x
Step-by-step explanation:
To solve this question, you will have to follow some specific principles to prevent error
So to solve this we will have to follow the BODMAS rule
9-3(45x+47x)-2+66
Deal with the bracket first
3(45x+47x)
3(92x)
276x
Then back to the question
9-276x-2+66
Collect like terms
9-2+66-276x
Add comes before substration according to bodmas
9+64-276x
55-276x
This cannot be solved further because they are different from each other
Therefore the final answer is 55-276x
