The mean radius of earth is 6371 kilometers and the the mean radius of earth's moon is 1737.5 kilometers. What is is the approxi
vaieri [72.5K]
The circumference is calculated through the equation,
                                C = 2πr
where C is circumference and r is radius.

Earth: 
                            C = 2π(6371 km)
                                = 40030.17 km

Moon:
                            C = 2π(1737.5 km)
                               = 10917.03 km
The difference between the two circumferences is approximately 29113.13 km.

What is a=h(b+c) (solve for b)
frosja888 [35]
1.  a=h(b+c)
2.  distribute the h:
         a=hb+hc
3.  move the 'hb' to the left:
         a - hb = hc
4.  subtract the a from both sides:
         -hb = hc - a
5.  divide both sides by -h to isolate b:
          b = -hc+a/h

Evaluate the surface integral. s x ds, s is the part of the plane 6x + 3y + z = 6 that lies in the first octant.
Musya8 [376]
The plane has intercepts at (1, 0, 0), (0, 2, 0), and (0, 0, 6), so we can parameterize the surface \mathcal S by

\mathbf r(u,v)=((1,0,0)(1-u)+(0,2,0)u)(1-v)+(0,0,6)v
\mathbf r(u,v)=((1-u)(1-v),2u(1-v),6v)

where 0\le u\le1 and 0\le v\le1. Now

\|\mathbf r_u\times\mathbf r_v\|=2\sqrt{46}(1-v)

so the surface integral reduces to

\displaystyle\iint_{\mathcal S}x\,\mathrm dS=2\sqrt{46}\int_{v=0}^{v=1}\int_{u=0}^{u=1}(1-u)(1-v)^2\,\mathrm du\,\mathrm dv=\frac{\sqrt{46}}3
