The edge of a cube was found to be 30 cm with a possible error in measurement of 0.5 cm. Use differentials to estimate the maxim

erica [24]

Answer with Step-by-step explanation:

We are given that

Side of cube, x=30 cm

Error in measurement of edge, $\delta x=0.5$ cm

(a)

Volume of cube, $V=x^3$

Using differential

$dV=3x^2dx$

Substitute the values

$dV=3(30)^2(0.5)$

$dV=1350 cm^3$

Hence, the maximum possible error in computing the volume of the cube

= $1350 cm^3$

Volume of cube, $V=(30)^3=27000 cm^3$

Relative error= $\frac{dV}{V}=\frac{1350}{2700}$

Relative error=0.05

Percentage error= $0.05\times 100=5$ %

Hence, relative error in computing the volume of the cube=0.05 and

percentage error in computing the volume of the cube=5%

(b)

Surface area of cube, $A=6x^2$

$dA=12xdx$

$dA=12(30)(0.5)$

$dA=180cm^2$

The maximum possible error in computing the volume of the cube= $180cm^2$

$A=6(30)^2=5400cm^2$

Relative error= $\frac{dA}{A}=\frac{180}{5400}$

Relative error in computing the volume of the cube=0.033

The percentage error in computing the volume of the cube= $0.033\times 100=3.3$ %

Calculate the area<br> shaded<br> of<br> segment

Mamont248 [21]

Answer:

10.45

Step-by-step explanation:

A=pi10^2*63/360-10*10 sin63/2=3.14*6300/360-50*0.89

A=3.14*17.5-44.5=54.95-44.5=10.45

or if I do not complete pi=3.14

A=17.5 pi-44.5
