The angle of sine has a value of 3/5.

Option A is the correct representation of angle sin(b°).

<h2>How do you calculate the angle b for sine?</h2>

Given that tan(b°) = 3/4 and cos(b°) = 4/5.

In trigonometry, we know that,

\dfrac {sin \theta}{cos \theta} = tan \theta

The angle of sine can be written as below.

sin \theta = cos \theta \times tan \theta

For the angle b, the above expression can be written as,

sin (b^\circ) = cos (b^\circ) \times tan (b^\circ)

Substituting the values in the above expression, we get,

sin (b^\circ) = \dfrac {3}{4} \times \dfrac {4}{5}

sin (b^\circ) = \dfrac {3}{5}

Hence we can conclude that the angle of sine has a value of 3/5.

To know more about the angle of sine, follow the link given below.

Cylinder: First you need to find the radius. To do that, you need to divide the diameter by 2

Then, you multiply it by itself

After that, you multiply it by the height

And finally multiply it by pi

Cone: First, you need to find the radius dividing the diameter by 2

Then, multiply it by itself

After that, divide the height by 3

Finally, multiply the radius times the height and then multiply it by pi

The answer to the cylinder is 251.2 and the answer to the cone is 251.2

The processes are the following:

Cylinder

D:8

R:4

V:π4^2*5

V:π16*5

V:80π

V:251.2

Cone

D:8

R:4

V:π4^2 15/3

V:π16*5

V:80π

V:251.2
