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 do I solve this problem?
slava [35]
I think it's 25. area is length times width aka...5 X 5 if you take the length times width of the tiles it's 1.

1x = 25 divide both sides by 1...

x ( number of tiles) = 25

Estimate the square root to the nearest (a) whole number and (b) tenth. Make sure you list 2 answers for these problems.
Aleksandr-060686 [28]

Answer:

  • -15i
  • -14.8i

Step-by-step explanation:

<h3>(a)</h3>

The nearest squares to 220 are 14² = 196 and 15² = 225. Since 220 is closer to 225 than to 196, the nearest whole number to the square root of 220 is 15.

The square root of -220 is imaginary, so the nearest whole number value will be 15i.

__

<h3>(b)</h3>

The decimal fraction part of the root can be estimated from the nearest squares to be ...

  (220 -196)/(225 -196) ≈ 0.828

Then the root of 220 to the nearest tenth is 14.8. The root of -220 to the nearest tenth will be the imaginary number 14.8i.
