A circle with area 16pi has a sector with a central angle of 8/5pi radians. What is the area of the sector?

lianna [129]

Answer:

The area of the sector is $12.8\pi\ units^2$

Step-by-step explanation:

we know that

The area of a complete circle (16π units^2) subtends a central angle of 2π radians

using proportion

Find out the area of a sector , if the central angle is equal to 8π/5 radians

$\frac{16\pi}{2\pi}=\frac{x}{(8\pi/5)}\\\\x=8(8\pi/5)\\\\x= 12.8\pi\ units^2$

Answer:

C. 300=60+30w

Step-by-step explanation:

Given:

Price of television-$300

Initial Payment-$60

Weekly payments-$30

Let weekly payments be w:

The initial payment plus the weekly installments should be equivalent to the television price:

$300=60+30w\\\\240=30w\\\\w=8$
