The circumference of a sphere was measured to be 78 cm with a possible error of 0.5 cm. (a) Use differentials to estimate the maximum error in the calculated surface area. (Round your answer to the nearest integer.) cm2 What is the relative error

The maximum error is  

Relative error is Relative error is =

Step-by-step explanation:

Circumference of a sphere C = 2

Differentiate above equation with respect to r

Given that

Surface area of the sphere S =

Differentiate above equation with respect to r

Where C = circumference of the sphere

given that C = 78 cm  &

So the maximum error is given by

Now the relative error is given by

Relative error =

⇒

Since

Relative error is =

Therefore the maximum error is  

Relative error is Relative error is =

the most boring ever written

step-by-step explanation:

i am writing something. yes, i plan to make it the most boring thing ever written. i go to the store. a car is parked. many cars are parked or moving. some are blue. some are tan. they have windows. in the store, there are items for sale. these include such things as soap, detergent, magazines, and lettuce. you can enhance your life with these products. soap can be used for bathing, be it in a bathtub or in a shower. apply the soap to your body and rinse. detergent is used to wash clothes. place your dirty clothes into a washing machine and add some detergent as directed on the box. select the appropriate settings on your washing machine and you should be ready to begin. magazines are stapled reading material made with glossy paper, and they cover a wide variety of topics, ranging from news and politics to business and stock market information. some magazines are concerned with more recreational topics, like sports card collecting or different kinds of hairstyles. lettuce is a vegetable.
