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:
pi
Step-by-step explanation:
pi is the way us pi and radius
Answer:
8.6%
Step-by-step explanation:
To find the percent change, you will need to compute the positive difference and then divide the difference by the original (the older amount).
So the positive difference will be obtain by doing larger minus smaller:
6300
- 5800
-----------
500
The older amount was 5800.
So 500/5800 is the answer as a un-reduced fraction.
I'm going to reduce it by dividing top and bottom by 100:
500/5800 = 5/58
5/58 is the answer as a reduced fraction.
5 divided by 58 gives=0.086206897 in the calculator .
Approximately 0.0862 is the answer as a decimal.
To convert this to a percentage, multiply it by a 100:
8.62%
Rounded to the nearest tenths is 8.6%
-------------
So 5800+5800(.0862) should be pretty close to 6300 (not exactly though since we rounded).
5800+5800(.0862)=6299.96 using the calculator.
Answer:
the formula to find slope is m=y1-y2/x1-x2
using this formula 8-6/8-(-4)
=2/8+4
=2/12 simplify
=1/6
