These ratios are equivalent because 7 and 8 can be multiplied by 6 to get 42 and 48.

Hello!
So you will use the Pythagorean Theron equation which is Asquare + bsquare=C square
Plug in what you are given to find the missing piece
A square+ (2.6)square= (6.2) square
Asquare+ 6.76= 38.44
(Subtract 6.76to both sides to isolate A)
Asquare= 31.68
(Take the square root of both sides to find out what A is)
A=5.628
Answer:
![\large\boxed{H=135\ cm}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7BH%3D135%5C%20cm%7D)
Step-by-step explanation:
The formula of a volume of a cylinder:
![V=\pi r^2H](https://tex.z-dn.net/?f=V%3D%5Cpi%20r%5E2H)
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](https://tex.z-dn.net/?f=V%3D%5Cpi%2812%5E2%29%2820%29%3D%5Cpi%28144%29%2820%29%3D2880%5Cpi%5C%20cm%5E3)
The formula of a volume of a cone:
![V=\dfrac{1}{3}\pi r^2H](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7B1%7D%7B3%7D%5Cpi%20r%5E2H)
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](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B3%7D%5Cpi%288%5E2%29H%3D2880%5Cpi%5Cqquad%5Ctext%7Bdivide%20both%20sides%20by%7D%5C%20%5Cpi%5C%5C%5C%5C%5Cdfrac%7B1%7D%7B3%7D%2864%29H%3D2880%5Cqquad%5Ctext%7Bmultiply%20both%20sides%20by%203%7D%5C%5C%5C%5C64H%3D8640%5Cqquad%5Ctext%7Bdivide%20both%20sides%20by%2064%7D%5C%5C%5C%5CH%3D135%5C%20cm)
