Let's solve for x.<span><span><span>rs</span>x</span>=<span>14
</span></span>Step 1: Multiply both sides by x.<span><span>rs</span>=<span><span>14</span>x
</span></span>Step 2: Flip the equation.<span><span><span>14</span>x</span>=<span>rs
</span></span>Step 3: Divide both sides by 1/4.<span><span><span><span>14</span>x</span><span>14</span></span>=<span><span>rs</span><span>14</span></span></span><span>x=<span><span>4r</span>s
</span></span><u>Answer:</u><span>x=<span><span>4r</span><span>s</span></span></span>
The volume of a sphere is V=4/3*pi*r^3
Since pi=3.14 and r=20, we have:
V=4/3*3.14*20^3
V=4/3*3.14*8000
V=4/3*25120
V=33493.33333
So the volume is about 33493 1/3 mm^3
Hope this helped!
L= 4*B+42
L= the load
B is the weight of each brick
42 is the weight of the carrier
