The circumference of a sphere was measured to be 74 cm with a possible error of 0.5 cm. (a) Use differentials to estimate the ma

larisa86 [58]

Answer Step-by-step explanation:

Circumference of sphere=74 cm

Error=0.5 cm

a.We know that circumference of sphere= $C=2\pi r$

Using the formula

$74=2\pi r$

$r=\frac{74}{2\pi}=\frac{37}{\pi}$

$C=2\pi r$

Differentiate w.r.t r

$\frac{dC}{dr}=2\pi$

$dC=2\pi dr$

$dr=\frac{dC}{2\pi}=\frac{0.5}{2\pi}$

Surface area of sphere= $S=4\pi r^2$

Maximum area in the surface area= $dS=8\pi rdr$

$dS=8\pi\times \frac{37}{\pi}\times \frac{0.5}{2\pi}=23.5\approx 24 cm^2$

Hence,the maximum area in the surface area=24 square cm

Relative error= $\frac{\Delta S}{S}\approx \frac{dS}{S}$

$\frac{\Delta S}{S}=\frac{8\pi rdr}{4\pi r^2}=2\frac{dr}{r}=2\times \frac{\frac{0.5}{2\pi}}{\frac{37}{\pi}}=2\times \frac{0.5}{2\pi}\times \frac{\pi}{37}=0.014$

Hence, the relative error=0.014
