Answer:
question one is 2,251.02
question 2 is 579.58
Step-by-step explanation:
Answer:
r = 
Step-by-step explanation:
A = πr-32
using algebraic manipulation to isolate r
A + 32 = πr-32 + 32
A + 32 = πr
(A+32)/π = πr/π
r =

How do you know, it has no solution
The expression on the left-hand side is an absolute function and the result is always positive.
However, the expression on the right-hand side shows a negative sign.
The negative sign is on the contrary to what an absolute value represent.
<em></em>
<em>Hence, it has no solution.</em>
15²-9²= x² use Pythagoras' theorum and square the two smaller sides to get the square of the hypotenuse (the diagonal) then rearrange this to get the above calculation
