The circumference of a sphere was measured to be 82 cm with a possible error of 0.5 cm. (a) Use differentials to estimate the ma
NeTakaya

Answer:

The Maximum error is  26cm^2

Step-by-step explanation:

Given that the circumference of a sphere was measured to be 82 cm with a possible error of 0.5 cm

<h3>To find :</h3><h3>(a) Use differentials to estimate the maximum error in the calculated surface area. (Round your answer to the nearest integer.) cm^2</h3>

Given circumference of a sphere=82 cm and possible error =0.5 cm

Error of the surface area is dA

Error of circumference is dC = 0.5 cm

We know that the formula for  Circumference of a sphere is C=2πr units  

Differentiating with respect to r

 dC = 2\pi dr

dr =\frac{dC}{2π}

=\frac{0.5}{2\pi} (∵ dC = 0.5 cm)

<h3>Since Area  A = 4\pi r^2 square units</h3>

Differentiating with respect to r

dA = 8\pi rdr  square units

Since given C = 82 cm.and also C=2πr  we have

r=\frac{C}{2π}

=\frac{82}{2π}

r=\frac{41}{π}

From that dA = 8\pi rdr

Substituting the values of r and dr in the above equation we get

dA = 8\pi (\frac{41}{\pi}) (\frac{0.5}{2\pi})

=4(41)\times (\frac{0.5}{3.14})

=26.1146

dA=26cm^2

∴  Maximum error is  26cm^2

marissa [1.9K]
Hello:
x/4 = 28  ....   x = 112
x/4 = 30  ....   x =  120
x/4 = 32  ....   x =   128
x/4 = 34  ....   x =  136
x/4 = 36  ....   x =   144
the domain is :   <span>{112,120,128,136,144}</span>
