When finding missing side measures in a right triangle.

Soh = (Sine = Opposite / Hypotenuse)

Cah = (Cosine = Adjacent / Hypotenuse)

Toa = (Tangent = Opposite / Adjacent)

There are also reciprocals for these values:

Cho (Cosecant = Hypotenuse / Opposite)

Sha (Secant = Hypotenuse / Adjacent)

Cao (Cotanget = Adjacent / Opposite)

Three cylinders have a volume of 2826 cm. Cylinder A has a height of 900 cm. Cylinder B

makkiz [27]

Answer:

the radius of each cylinder is 1 cm, 2 cm and 3 cm respectively

Step-by-step explanation:

The computation of the radius of each cylinder is shown below:

As we know that

The Volume of the cylinder = πr^2h

The radius would be

$=\sqrt{ \frac{V}{\pi h} }$

For cylinder A

$=\sqrt{\frac{2826}{3.14\times 900} }$

= 1 cm

For cylinder B

$=\sqrt{\frac{2826}{3.14\times 225} }$

= 2 cm

For cylinder C

$=\sqrt{\frac{2826}{3.14\times 100} }$

= 3 cm

Hence, the radius of each cylinder is 1 cm, 2 cm and 3 cm respectively
