What is the general form of the equation of the given circle with center A

1 answer:

7 0

If center A is at the point (h, k), the formula for the circle is r^2 = (x-h)^2+(y-k)^2, where r is the radius of the circle

Answer:

60.6528 kg

Step-by-step explanation:

Assuming the solid ball of iron is a sphere with a radius of 18 cm (or 0.18 m), we can compute the volume of the sphere:

$V=\frac{4}{3}\pi r^3\\\\V=\frac{4}{3}\pi (\frac{18}{100})^3\\\\V=\frac{4}{3}\pi (0.005832)\\\\V=0.007776$

Therefore, the volume of the solid ball is 0.007776 m³

Since we know that density is mass/volume, then we can find the mass of the iron:

$\rho=\frac{mass}{volume}\\ \\7800\: kg/m^3=\frac{mass}{0.007776\: m^3}\\\\mass=60.6528\:kg$

Thus, the mass of the solid ball of iron is 60.6528 kg

A) 2 2/9

The answer would of course be positive because two negatives make a positive.

It would only be 6 4/9 if you added when here it states the obvious for you to subtract.
