Question

Solve the formula for the specified variable. I don't understand the following:

s=2*pi*r*h + 2*pi*r^2 for h
-the options for this one are:
a. h=(s)/(2*pi*r)-1
b. h=2*pi(s-r)
c. h=(s-2*pi*r^2)/2*pi*r
d.h=s-r


A=P(1+nr) for r
-the options for this one are:
a. r= a-p/pn
b.r=a/n
c.r= p-a/pn
d. r= pn/a-p

1. Check whether you copied option "a" correctly. Unless the last term is r instead of 1, none of the choices are correct.
2. Unless there are parentheses around (a-p), noe of the choices are correct. Try to avoid mixing up upper and lower case sumbols.
