Answer:

C. -0.6

Explanation:

Line is passing through the points ( - 3, 1) & (2, - 2)

Slope of line

$= \frac{ - 2 - 1}{2 - ( - 3)} = \frac{ - 3}{2 + 3} = \frac{ - 3}{5} = - 0.6 \\$

An iron sphere of radius 0.18m has mass 190 kg. Calculate the density of the iron

Slav-nsk [51]

radius=r=0.18m

Volume:-

$\\ \sf\rightarrowtail \dfrac{4}{3}\pi r^3$

$\\ \sf\rightarrowtail \dfrac{4}{3}\pi (0.18)^3$

$\\ \sf\rightarrowtail \dfrac{4}{3}\pi (0.005832)$

$\\ \sf\rightarrowtail 0.024m^3$

Mass=190kg

Density:-

$\\ \sf\rightarrowtail \dfrac{Mass}{Volume}$

$\\ \sf\rightarrowtail \dfrac{190}{0.024}$

$\\ \sf\rightarrowtail 7916.67kg/m^3$
