The central angle of an arc measures 120° The radius of the circle measures 3 cm what is the area of the sector to the nearest h

jeka57 [31]

Answer:

The area of the sector should be 9.42 $cm^2$ .

Step-by-step explanation:

-The formula for finding the area of a sector:

$A = \frac{Arc}{360} \pi r^2$

-Next use the arc measure and the radius in order to solve and get the answer:

$A = \frac{120\textdegree}{360\textdegree}\pi 3^2$

-Solve:

$A = \frac{120\textdegree}{360\textdegree}\pi 3^2$

$A = \frac{120\textdegree}{360\textdegree}\pi \times3^2$

$A = \frac{1}{3} \pi \times 3^2$

$A = \frac{1}{3} \pi \times 9$

$A = 3\pi \approx 9.424$

-Round to the nearest hundredth:

$A \approx 9.42$

Is this a right triangle why or why not?

Marysya12 [62]

Answer:

No, it does satisfy the Pythagorean Theorem

Step-by-step explanation:

In right triangle a² + b² = c²

Where a and b = legs and c = hypotenuse

The given measures of the legs are 3 and 7 and the given measure of the hypotenuse is √57

Which means that if this is a right triangle then 3² + 7² = √57²

3² = 9

7² = 49

√57² = 57

9 + 49 = 58

we're left with 57 ≠ 58 which is not true, meaning that , that is not a right triangle

Someone pls help I need this like now pls lots of points and brainliest

Serjik [45]

Answer:

See below

Step-by-step explanation:

5⁵(16²5³)³ = 5⁵(2⁴)³(5³)³ = 5⁵2¹²5⁹ = 5¹⁴2¹²

(8⁴5³/8⁵)² = (5³/8)² = (5³)²/(2³)² = 5⁶ / 2⁶

(5⁸3⁷/5⁴)¹⁰ = (5⁴3⁷)¹⁰ = (5⁴)¹⁰(3⁷)¹⁰ = 5⁴⁰3⁷⁰

<u>Multiplying powers with same base:</u>

$a^b*a^c=a^{b+c}$
Same base with powers added up

<u>Multiplying powers with same exponent but different base:</u>

$a^b*c^b=(ac)^b$
Same exponent with bases multiplied

Pls help , need this done by tomorrow.

quester [9]

Answer:

Q matches to a and P matches to b

Step-by-step explanation:

This is a volume question so we can use the volume of a cylinder to see which one corresponds to what. Volume of a cylinder is $\pi$ $r^{2}$ h. We know that the heights of the cylinders are the same since the diagram says so. We also know pi is the same since thats a constant. The only thing thats different is the radius (as you can see radius of P is bigger than Q). If the radius of P is bigger than Q and all the other things are the same (height is the same and pi is the same), then that automatically means that P has more volume than Q. More volume means more time to fill up. Since Q has less volume, it will take less time to fill up. So now we look at the graph. A shows that the height of water increases at a faster rate than that of B. This is because there is less volume in that container (less volume=less time to fill up). Therefore a matches to Q and therefore b matches to P
