Answer:

Step-by-step explanation:

Cylinder volume= V = π r ^2 h

So you times Pie by the radius (diametre divided by two- 3.5) you then square this. After that, times it by the height (10)

So the volume is 384.85.

You then find 30% of this, so times 384.85 by 30%.

You then get an answer of 115.455, and this is equal to A.

I hope this helps, have a lovely day.

“angle A = 32, AC = 9, BC = x. Find x to two decimal places, don’t forget to round properly based on the third decimal place.” P

Liono4ka [1.6K]

<u>Given</u>:

Given that ABC is a right triangle.

The measure of ∠A is 32°.

The length of AC is 9 units.

The length of BC is x units.

We need to determine the value of x.

<u>Value of x:</u>

The value of x can be determined using the trigonometric ratio.

Thus, we have;

$sin \ \theta=\frac{opp}{hyp}$

where θ = A, the side opposite to A is BC and hypotenuse is AC.

Thus, we have;

$sin \ A=\frac{BC}{AC}$

Substituting BC = x and AC = 9, we get;

$sin \ 32=\frac{x}{9}$

Multiplying both sides by 9, we have;

$sin \ 32 \times 9=x$

$4.77=x$

Thus, the value of x is 4.77 units.
