Answer:
The Maximum error is 
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.)

</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 = 0.5 cm)
<h3>Since Area

square units</h3>
Differentiating with respect to r
square units
Since given C = 82 cm.and also C=2πr we have



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




∴ Maximum error is 
Answer:

Step-by-step explanation:
possible derivation:
(a 26.6)
Factor out constants:
= 26.6 [
(a) ]
the derivative of a is 1 :
= 1 26.6
Exact form: 112/5
decimal form: 22.4
mixed number form: 22 2/5
Answer:
x = 7
Step-by-step explanation:
all we know is that she had 1 brownie at the end, in the end she gave half her brownie to tyler, so add one who will get 1 1/2, before that she split her brownies between her friends, so multiply 1 1/2 by 2 and you will get 3, before that she gave 1/2 a brownie to Kiran, so we would add 1/2 to 3 and get 3 1/2, before that she first split it in half for a her friends, so at last, multiply 3 1/2 by 2 and you will geet 7 as your final answer.
