Question

A candle has a volume of 3217 cm3. Determine the minimum amount of plastic that is needed to cover the outside of the candle for packaging and find the dimensions of the candle that produces this surface area. [Assume the candle has a cylindrical shape ] show all your steps.

Answer 1

Answer:-

After putting x=2 in equation, we get −1.

After putting x=−1, we get 8

After putting x=21, we get 45

So, p(2)−p(−1)+p(21)=−1−8+45

=−9+45=4−36+5=4−31

Hope that helps..!!
