Answer:

solution here

length

c=170

a=162

b=177

perimeter=?

now,

perimeter of triangle = a+b+c

=170+162+177

=511

perimeter=511 cm

perimeter = length of fence

therefore,the fence should be 511 cm long.

Answer:

sorry to answer late but..

Step-by-step explanation:

$\frac{1}{75} cm$ = $\frac{scale }{real}$

the wings of the real plane are 12 meters or 1200 cm

we want to solve for the scale, sooo do the algebra...get scale by it self..

real * $\frac{1}{75}$ = scale

1200 * $\frac{1}{75}$ = 16

The scale model wings are 16 cm 2.54 cm is one inch so the wings are approx. 6.3 inches

The area of the top face of a cube is 49cm^3. What is the volume of th cube?

Vlad1618 [11]

Answer:

$V=2401cm^{3}$

Step-by-step explanation:

The fact that the figure is a cube means all sides, faces, and corners are equal.

$V=BHW$

$V=49cm^{2}(W)$

$V=49cm^{2}(49cm)\\ V=2401cm^{3}$

How to find the volume of the cone

gavmur [86]

Answer:

The closest measurement to the volume of hat is 84.82 in.³.

Step-by-step explanation:

Given:

The dimensions of hat are height(h) 9 inches and diameter(d) 6 inches.

Now, to find the volume of cone:

Putting the formula $\frac{1}{3}\pi r^{2}h$ .

Radius(r) is not given, finding the radius:

Radius(r)=half of the diameter(d)

$r=\frac{d}{2}$

$r=\frac{6}{2}$

$r=3$ .

Then, $\frac{1}{3}\pi r^{2}h$

= $\frac{1}{3}\times\pi \times3^{2}\times9$

= $\frac{1}{3}\times3.14\times9\times9$ ( $\pi =3.14$ )

= $\frac{1}{3} \times254.34$

= $\frac{254.34}{3}$

= $84.78$ in.³

So, the volume is 84.78 in.³ .

Therefore, the closest measurement to the volume of hat is 84.82 in.³.

what is the maximum volume of water for a hamster bath could hold with a depth of 1 2/3 inches, a length of 2 1/3 inches, and wi

maksim [4K]

Volume = length x width x height

So,
Volume = 2 1/3in x 2in x 1 2/3in
Volume = 7/3in x 6/3in x 5/3in
Volume = 210/9in^3
Volume = 70/3in^3 or 23 1/3in^3
