Answer:

15.5 ft²

Step-by-step explanation:

The area (A) of a regular polygon is calculated as

A = $\frac{1}{2}$ pa ( p is the perimeter and a the apothem )

Here side of regular pentagon is 3 ft, thus

perimeter = 5 × 3 = 15, so

A = 0.5 × 15 × 2.06 ≈ 15.5 ft ( to the nearest tenth )

I would first find the volume of the hole and multiply that by 2 because there's 2 holes.

$v = lwh$

$v = (5)(8)(5)$

$v = 200$

$200 \times 2 = 400$

I would then find the volume of the entire cinder block.

$v = lwh$

$v = (16)(8)(8)$

$v = 1024$

I would then substract.

$1024 - 400 = 624$

The volume of the cinder blocks is 624 inches³

You put the -2 over a 1, and a 1 under the -3. On the y axis, go to -2 and put a dot. Go down three, and right one. To go up, you go up three and left one.
