The circumference of a sphere was measured to be 76 cm with a possible error of 0.2cm.

1. Use differentials to estimate the maximum error in the calculated surface area.

2. What is the relative error in the calculated surface area?

_____cm^2

_________%

3.Use differentials to estimate the maximum error in the calculated volume.

______cm^3

4.What is the relative error in the calculated volume? Please round the answer to the nearest tenth.

_____%

C= 2PI r
dC= 2PI dr
dr= dC/2PI

S= 4PI r^2
dS= 8PI r dr= 8PI r/2PI dC=2C/PI dC
check my thinking

Solve for dS given C, and dC

i'll try it out thanks
