Answer:

≈ 1800 mm³

Step-by-step explanation:

Volume of the figure above will be given by the formula

Cross section area × length

In this case;

Cross section area will be;

Area of the square + area of the two semi circles

12× 12 + 2(3.14 × 6 ×6/2)

= 144 + 3.14 ×36

= 257.04 mm²

Volume = Cross section area × Length

= 257.04 × 7

= 1799.28 mm³

<u> ≈ 1800 mm³</u>

stellarik [79]

Answer:

2x + 1.

Step-by-step explanation:

y=x^2 + x + 1

Using the algebraic derivative rule, if y = ax^n then y' = anx^(n-1) :

The derivative is 2x^(2 - 1) + 1x^(1-1)

= 2x^1 + x^0
