Answer: $24\pi\text{inches}^2$

Step-by-step explanation:

The area of sector with central angle 'x' ( in degrees) and radius 'r' is given by :-

$\text{Area of sector}=\dfrac{x}{360}\times\pi r^2$

Then the area of sector with central angle $60^{\circ}$ and radius 12 inches is given by :-

$\text{Area of sector}=\dfrac{60}{360}\times\pi (12)^2\\\\\Rightarrow \text{Area of sector}=24\pi\text{inches}^2$

Sandra rode her bike 5 times as many miles as Barbara. If b, the distance Barbara rode, equals 3.4 miles, what is the correct ex

uranmaximum [27]

Well, Sandra would've had to ride her bike 17 miles, so the answer is b because when a number is next to a letter, you have to times it. So, 5 times by b equals 17, so that is the answer. Hope it helps!

If X=3+√8, find X square + 1/x square

irina1246 [14]

Given :-

x = 3 + √8

To find :-

x² + 1/x²

Solution :-

According to Question,

x = 3 + √8
1/x = 1/3-√8
1/x = 1(3+√8)/(3+√8)(3-√8)
1/x = 3+√8/3²-(√8)²
1/x = 3+√8/9-8
1/x = 3 + √8

So that ,

x² + 1/x²
(x + 1/x)² - 2
( 3+√8+3-√8)²-2
9² - 2
81 - 2

A circular plate has a radius of 13 centimeters.

Tamiku [17]

Answer: $A=530.66\ cm^2$

Step-by-step explanation:

For this exercise it is necessary to remember that the area of a circle can be calculated with the following formula:

$A=\pi r^2$

Where "A" is the area of the circle and "r" is the radius of the circle.

In this case, based on the information given in the exercise, you know that the circular plate has the following radius:

$r=13\ cm$

Therefore, knowing the radius, you can substitute them into the formula and finally, you must evaluate in order to calculate the area of the plate (Remember that you must use 3.14 for $\pi$ ).

Then, you get that this is:

$A=\pi r^2\\\\A=(3.14)(13\ cm)^2\\\\A=530.66\ cm^2$
