Answer:

90

Step-by-step explanation:

Partition the figure by extending the sides of the ``middle'' square as shown at the right. Each original square contains four $3 \times 3$ small squares. The shaded figure consists of ten $3 \times 3$ squares, so its area is $10 \times 9 = \boxed{90\text{ square

units}}$.

Ghella [55]

Answer:

The area of the base is = 5.2 cm²

Step-by-step explanation:

<em>First, we need to know the formula to calculate volume:</em>

$volume=height XBase area$

<em>if we change to our equations to the values we know:</em>

$16.328 = 3.14XB$

<em>Since 3.14 is multiplying B,we can pass it to divide the volume to the left side:</em>

$\frac{16.328}{3.14} =B$

<em>We calculate the operation=</em>

$\frac{16.328}{3.14} =5.2$

<em>And the answer is 5.2 cm²</em>

<em>Let me know if you have any question :D</em>
