if the height of the cylinder with a radius of 12 cm and a height of 20 cm has the same volume as a cone with a radius of 8 cm.
Marrrta [24]

Answer:

\large\boxed{H=135\ cm}

Step-by-step explanation:

The formula of a volume of a cylinder:

V=\pi r^2H

r - radius

H - height

We have the radius r = 12cm and the height H = 20cm. Substitute:

V=\pi(12^2)(20)=\pi(144)(20)=2880\pi\ cm^3

The formula of a volume of a cone:

V=\dfrac{1}{3}\pi r^2H

r - radius

H - height

We have the radius r = 8cm and the volume V = 2880πcm³. Substitute:

\dfrac{1}{3}\pi(8^2)H=2880\pi\qquad\text{divide both sides by}\ \pi\\\\\dfrac{1}{3}(64)H=2880\qquad\text{multiply both sides by 3}\\\\64H=8640\qquad\text{divide both sides by 64}\\\\H=135\ cm

Step-by-step explanation:

A reflection is a transformation representing a flip of a image. images can be reflected in a plane, line, and point. When reflecting a image/figure in a line or in a point, the image is congruent to the preimage. A reflection maps every point of a figure to an image across a fixed line.
