Subtract:

523% × 10 = (523/100) × 10 = 52.3
Answer:
D = 12.94 m
Step-by-step explanation:
Coordinates of first tree = A(0,8)
Coordinates of second tree = A(12,4)
We need to find the distance between the two trees. We can find it using distance formula for coordinates as follows :

We have, x₁ = 0, x₂ = 12, y₁ = 8, y₂ = 4
Now using distance formula,

So, the distance between the two trees is 12.64 m.
Volume = pi x radius squared x height
v=3pixr^2x3
v=27pi
Answer: okay so first solve for x which is going to be x=10
