Answer:

Perimeter = 40.1 cm

Step-by-step explanation:

Finding CD for ΔCBD using Pythagorean theorem

c² = a² + b²

c² = 4.1² + 8.4²

c² = 16.81 + 70.56

c² = 87.37

Taking sqrt on both sides

CD = 9.35 cm

Now Finding CA of ΔCBA by Pythagorean theorem

c² = a² + b²

c² = 12² + 8.4²

c² = 144 + 70.56

c² = 214.56 cm

Taking sqrt on both sides

CA = 14.65 cm

Now Perimeter = Sum of all sides

= 14.65 + 9.35 + 12 + 4.1

= 40.1 cm

The cylinders are similar. The volume of the larger cylinder is 9648 cubic inches. What is the volume of the smaller cylinder?
zalisa [80]
Hey there :)

The volume formula of a cylinder is:
V = \pir²h

The volume of the larger volume is given to be 9648³ and the height is 18 in
We need to find the radius first

9648 = \pir²(18)
\frac{9648}{18} = \pir²
536 = \pir²
\frac{536}{ \pi} = r²
\sqrt{ \frac{536}{ \pi } } = r
r ≈ 13.06

The ratio of the big cylinder to small cylinder is:
18 : 9   (given height)
So the big cylinder is 2 times bigger than the small cylinder
Therefore the radius of the big cylinder is as well 2 times bigger

\frac{13.06}{2} = r
r ≈ 6.53  ( the radius of the small radius )

V (of small cylinder) = \pi(6.53)²(9)
                                  = 1206 in³

How does your model represent the problem?
Paha777 [63]

Answer:

the first equation is the total legs on one dog being added together with 2 other total dog legs. The second equation is the number of dogs multiplied by the total number of legs on one dog. Either way both equation show 3 dogs with 4 legs each.
