Given:

Radius of circle = 12 units

Area of sector = 24π sq. units.

Central angle = x

To find:

The value of x.

Solution:

We have,

r=12

A=24\pi

\theta = x

We know that, area of a sector is

A=\dfrac{\theta }{360^\circ}\pi r^2

Where, \theta is central angle, r is radius.

24\pi=\dfrac{x}{360^\circ}\pi (12)^2

24\pi=\dfrac{x}{360^\circ}\pi (144)

\dfrac{24\pi}{144\pi}=\dfrac{x}{360^\circ}

\dfrac{1}{6}=\dfrac{x}{360^\circ}

Multiply both sides by 360 degrees.

\dfrac{1}{6}\times 360^\circ=x

60^\circ=x

The value of x is 60 degrees.

Therefore, the correct option is A.

MA_775_DIABLO [31]

Answer:\frac{13}{21}

Step-by-step explanation:

2( N+ 17) = 3 (N +7)

2N+ 34= ·3N+ 21

N= 13

D= N+8 = 13+8 = 21

Fraction is \frac{13}{21}

When Im using N is equal to numerator and D for denominator, in order to get the fraction we substitute and the results combine in the fraction like this  \frac{N}{D}
