Answer
(a) $6.88\times 10^{-5}~m$
(b) $2600.00~km$
(c) $22~m^2$
(d) $= 0.01~cm$
(e) $= 0.013~cm$
Work Step by Step
(a) $6.85\times 10^{-5}~m+2.7\times 10^{-7}~m$
$= 6.85\times 10^{-5}~m+0.027\times 10^{-5}~m$
$= 6.88\times 10^{-5}~m$
(b) $702.35~km+1897.648~km$
$= 2600.00~km$
(c) $5.0~m \times 4.3~m = 22~m^2$
(d) $\frac{0.04}{\pi}~cm$
$= \frac{0.04}{3.14}~cm$
$= 0.01~cm$
(e) $\frac{0.040}{\pi}~cm$
$= \frac{0.040}{3.14}~cm$
$= 0.013~cm$
