moazzam07 · Answer

U know full angle of a circle is=360degree

mathstudent55 · Answer

$\Large A_{sector} = \dfrac{\theta}{360^o} \pi r^2$

moazzam07 · Answer

Let the angle makes by ur given sector is= theta

moazzam07 · Answer

area of s circle is=pi*r^2

mathstudent55 · Answer

You know A = 125.6 cm^2, r = 8 cm, pi = 3.14.
Enter all those values in the formula above and solve for the angle $\theta$ (Greek letter theta).

moazzam07 · Answer

3.14*4^2=?

moazzam07 · Answer

Required formula is
360/theta=50.24/12.56
Theta=?

thx for helping out guys

mathstudent55 · Answer

$\Large A_{sector} = \dfrac{\theta}{360^o} \pi r^2$

$\Large 125.6~cm^2 = \dfrac{\theta}{360^o} (3.14)(8~cm)^2$

Solve for $\theta$.

What did you get?

anonymous · Answer

i got .625

mathstudent55 · Answer

$\Large \dfrac{125.6~cm^2(360^o)}{3.14(64 ~cm^2)} = \theta$

mathstudent55 · Answer

You forgot to multiply by $360^o$
