Without solving explain why the equations do not have solutions
1 answer:
<h2>Examining the equation</h2>
We have 2 terms:
and
For the sum of these to equal a negative number, in this case -3, one of these terms would have to be negative.
<h2>So what's the problem?</h2>The function (square root of x) only returns positive values!
(See the attached image for a graph of )
Since neither of the terms can be negative, it can't be equal to -3. In other words, no matter what we put as , we can't solve the solution, so we say that the equation <em>does not have any solutions.</em>

Answer:
942
Step-by-step explanation :
so your d is 300 so your r = 300/2= 150
a=3.14*r*r= 3.14*150*150= 70650
c= 3.14*d= 3.14*300= 942

The curved surface area of solid cylinder is
As we are given that:
Diameter of solid cylinder = 8 cm
Length or Height o solid cylinder = 140 cm
Formula used to calculate the curved surface area of cylinder is:2n x h
Curved surface area of cylinder =2r x h
where,
r = radius of cylinder
h = height or length of cylinder
Radius of cylinder = daimeter
Now putting all the given values in above formula, we get:
Curved surface area of cylinder = 2x 22/7 x 140cm
Curved surface area of cylinder =
Therefore, the curved surface area of solid cylinder is3520cm^{2}
