In a circle, a 90degrees sector has area 144pi in2. What is the radius of the circle?

RUDIKE [14]

Answer:

The radius of the circle is 24 inches.

Step-by-step explanation:

Central angle in a sector is 90 degrees

Area of a sector is $144\pi\ \text{inch}^2$

The area of sector is given by the formula as follows :

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

r is the radius of circle

$r=\sqrt{\dfrac{360 A}{\theta \pi}} \\\\r=\sqrt{\dfrac{360 \times 144\pi }{90\times \pi}} \\\\r=24\ \text{inch}$

So, the radius of the circle is 24 inches.

marissa [1.9K]

1st Avenue would be more difficult because it’s rise and run is for every one foot forward it is 3 feet up. Meanwhile avenue 16th would start at (3,1) and the rise and run would be for every 3 feet it would go up 1 foot.

Answer:

(1, 0.25)

Step-by-step explanation:

To find when f(x)=g(x), then look for a value that is the same for both functions in the table. 0.25 occurs twice for the same x value. This is when they are equal. The solution is (1, 0.25).
