Answer:

Area= 7234.56

Step-by-step explanation:

area= πr²

diameter= 96

so that means radius is 48

$48^{2} \pi$ = 7234.56

Answer:

If the sine of an angle equals to {2}/{5}, then the tangent of the angle could be:

5. $\frac{2}{\sqrt{21} }$

Step-by-step explanation:

Imagine a triangle

The sine of an angle is equal to the length of the opposite leg over the hypotenuse.
HINT: SOHCAHTOA

To find the adjacent leg (a):

Using the pythagorean theorem: $a^{2} + b^{2} =c^{2}$

- a and b are the lenght of the sides and c is the hypotenuse

we know one side and the hypotenuse. Therefore plugging into the formula we get:

$a^{2} + 2^{2} =5^{2}$

where a is the adjacent leg of the triangle, solving for a we get:

$a^{2} =5^{2}- 2^{2}$

$a^{2} = 21$

$a = \sqrt{21}$

To find the tangent of the angle:

Since tangent is opposite leg over the adjacent leg:

tan θ = $\frac{2}{\sqrt{21} }$

2. Find the value of x and y in the given figure.

seropon [69]

As you can see, this is a multiplication root.

y = 4 · x

x = 7 · 3

So solve for x first to solve for y.

x = 7 × 3

x = 21

y = 4 · x

y = 4 × (21)

y = 84
