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

Solve the equation x/4 - 7 = y got x
Lina20 [59]

Answer:

x = y · 11

Step-by-step explanation:

Since x is divided by 4, we have to multiply each side by 4.

x-7=y · 4  To get x by itself, add 7 to each side to get x = y · 11

10(-3n + 8) = 380 pls find n
Flauer [41]

Answer:

n = - 10

Step-by-step explanation:

10(-3n + 8) = 380

-30n + 80 = 380

80 - 380 = 30n

30n = - 300

n = - 300 : 30

n = - 10
