Answer:
2√7
Step-by-step explanation:
Mathematically, the equation of a circle can be represented by;
(x-h)^2 + (y-k)^2 = r^2
where (h,k) = center and r = radius
Applying this to the question, we can see that the length of the radius of the circle is √7
The diameter is always twice the radius
Thus, the diameter KL = 2 * √7 = 2√7
Well, all we have to do is add, so:
6 + (-47) =
6 - 47 =
-41
Answer:
150cm2
Step-by-step explanation:
A=6a2, where a is the side of one face of the cube. Given a=5cm
A=6(5cm)^2
=6×25cm^2
=150cm^2 or 150cm2
