Answer:

B.135

Find the volume of this figure to the nearest whole number. Use 3.14 for pi.
sukhopar [10]

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>

Ne4ueva [31]
First you cancel 7 and 28, and 3 and 9, so that leaves you with 4/3 x 15/17, then you cancel 3 and 15 so you get 4x5/17 which should give you 20/17!

A zombie lost 3 limbs each day for 4 days.
blondinia [14]

Answer:

-12 tells us the amount of limbs lost.

Explanation:

-3 means that the zombie lost 3 limbs.

If the zombie loses three limbs every day for 4 days, it results in the zombie losing 12 limbs and so therefore -12.

-3 x 4 = -12

-12 is the product of the equation.

hope that helps
