Question

In a measurement of radius the percent of error is 15% then calculate percent of error in surface area and volume

Answer 1

Answer:

Surface area=30℅

Volume =45℅

Step-by-step explanation:

For surface area

$area = r^{2}$

$\%error = power \times radius \\ \\ error \: in \: radius(given) = 15\% \\ \%error = power \times radius = 2 \times 15 \\ = 30\%$

Now Volume

$\%error = power \times radius \\ \\ volume = {v}^{3} \\ \\ \%error \: in \: volume = 3 \times 15(given) \\ = 45\%$

Hope this will help..
