Answer:

Perimeter = 71

Step-by-step explanation:

angles formed by tangent lines has equal side lengths.

segments from A to tangent point = 17 each

segments from B to tangent point = 12 each (29 - 17 = 12)

segments from C to tangent point = 2.5 each

segments from D to tangent point = 4 each (21 - 17 = 4)

Perimeter = 2(17) + 2(12) + 2(2.5) + 2(4) = 71

Answer:

$V=45396.2\ cm^3$

Step-by-step explanation:

Given that,

The dimensions of an aquarium are 61 cm long, 30.5 cm wide, and 30.5 cm high.

The tank is filled to 80% capacity with water.

We need to find the water needed for this tank.

The volume of cuboid is given by :

$V=lbh$

As it is filled to 80% capacity, so,

$V=\dfrac{80}{100}\times lbh\\\\=0.8\times 61\times 30.5\times 30.5\\\\V=45396.2\ cm^3$

So, $45396.2\ cm^3$ of water is needed for this tank.
