Answer: 2218.41

Step-by-step explanation:

All you have to do is πr²

π = 3.14

π (15)²

15*3.14 = 47.1

47.1²

47.1*47.1 = 2218.41

alisha [4.7K]

Answer:

\sin \theta=-\frac{4}{5}

Step-by-step explanation:

Given:

Angle is in standard position which means the starting ray is at the origin. The terminal side has coordinates (3, -4).

So, the 'x' value is 3 and 'y' value id -4.

Using Pythagoras Theorem, we find the hypotenuse.

Hypotenuse = \sqrt{3^2+(-4)^2}=\sqrt{9+16}=\sqrt{25}=5

Now, using the sine ratio for the angle, we have

\sin \theta=\frac{Opposite}{Hypotenuse}\\\sin \theta=\frac{-4}{5}\\\sin \theta=-\frac{4}{5}

Therefore, the value of \sin \theta is -\frac{4}{5}.

The value is negative as the point (3, -4) lies in the fourth quadrant and sine ratio is negative in the fourth quadrant,

Answer:

I'm pretty sure the answer is 48 feet.

Step-by-step explanation:

It can't be any of the negative answers since the question didn't start with a negative number, and it can't be 14 feet since he started with 15 feet, so it has to be 48 feet.

Value of y???????pls help
Flura [38]
Since two sides are congruent, the opposite angles are congruent.
Angles A and B have the same measure.

m<A = m<B = 34

m<A + m<B  m<C = 180

34 + 34 + m<C = 180

68 + m<C = 180

m<C = 112

m<C = 4y = 112

4y = 112

y = 28

Pleaseeeeee help i will mark brainlest
NNADVOKAT [17]

Answer:

e°=100°

Step-by-step explanation:

Sum of angles in a triangle= 180°

70°+30°+x°=180°

100°+x=180

Collect like terms

x°=180-100

x°=80°

e° is an exterior angle

exterior angle =180- interior angle

180°- x°

180°- 80°

=100°

e°=100°
