Answer:
r = √(A/π)
Substitute area into "A", then solve:
Divide A by π, then find the square root of that number.
Explanation:
With the area of a circle, you can find the radius by rearranging its formula.
Area of a circle: A = πr²
<u>Rearrange the formula to isolate "r"</u>.
A = πr²
A/π = πr²/π Divide both sides by π
A/π = r² π divided by π cancels out on the right
√(A/π) = √r² √ both sides to cancel out ²
√(A/π) = r Write "r" on the left for standard formatting
r = √(A/π) Formula for find radius
If you have the area, use this formula.
- Substitute "A" with the area.
- Divide A by π
- Find the square root of that number

Answer:
Option A
x=6 , y=9
Step-by-step explanation:
As we can see in the figure that point T is the mid point of rectangle and there are two diagonals QS and PR
So in basic geometry we know that the length of the diagonal from the mid point i.e. Taking the diagonal QS the length of QT and TS would be equal because they are same diagonal which is cut into two parts by point T
Similarly the Length of RT and the length of TP would be same
From all this we deduct that
3x = 2y ..................(i)
and
y + 3 = 2x ................(ii)
From equation (i)
3x = 2y
Dividing both sides by 3 the equation becomes
x=
....................(iii)
Putting this value in equation (ii)
y + 3 = 2(
)
y+3 =
multiplying both sides by 3
3(y+3)=
the equation becomes
3y+9=4y
subtracting 3y from both sides
3y-3y+9=4y-3y
y=9
Putting the value of y in equation (iii)
x= 
solving it
x= 
x=6
so x=6 and y=9 is answer which is option A

62.5%, Because you do 5 divided by 8 that would be 0.625. move te decimal over two places and you have your percent.
