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

<em>L= 9.086 feet</em>

Step-by-step explanation:

<u>Area of a Circular Sector</u>

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 &amp; 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.
