A)a closed tin of milk has diameter 10cm and height 16cm. find the total surface area of the tin, pi=3.14
b)given that v=pi r²h, make r the subject of the fomula
c) using the result from b above ,find the value of r when v =81 cm³,pi=4 and h=9cm

Step-by-step explanation:

hope u understand

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
