If the area of a sector is 100 ft^2 and the radius of the circle is 22 ft what is the central angle measure for that sector and

ahrayia [7]

Answer:

$\displaystyle \theta=0.413\ rad$

L= 9.086 feet

Step-by-step explanation:

Area of a Circular Sector

Given a circle of radius r, the area of a circular sector defined by a central angle θ (in radians) is given by

$\displaystyle A=\frac{1}{2}r^2\theta$

And the length of the arc is:

$L=\theta r$

We know the area of the sector is 100 square feet and the radius is r=33 ft, thus:

$\displaystyle 100=\frac{1}{2}r^2\theta$

Solving for θ:

$\displaystyle \theta=\frac{200}{r^2}$

$\displaystyle \theta=\frac{200}{22^2}$

$\displaystyle \theta=0.413\ rad$

The arc length is:

$L=0.413* 22$

L= 9.086 feet

TJ bought 3 t-shirts & a pair of shorts for $15. If each shirt was $4.25, how much were the shorts?

Simora [160]

$4.25 \times 3 = 12.75$

That was the total of the 3 t-shirts.

$15 - 12.75 = 2.25$
That's the price for the shorts.
