The radius of the sector of the circle with the given area is: B. 3.

<h3>What is the Area of a Sector?</h3>

Area of sector of a circle = ∅/360 × πr².

Given the following:

Area of sector = 9/8 π cm².

∅ = 45 degrees

Plug in the values into the formula

9/8π = 45/360 × πr²

1.125 = 0.125 × r²

1.125/0.125 = r²

9 = r²

r = 3 cm

What is the equation of a circle whose radius is 16 units and center is at (2,-5)?

STatiana [176]

Answer:

The general equation of the circle is
$( {x - a})^{2} + ({y - b})^{2} = {r}^{2} \\ therefore \: we \: \: have \: \\ ( {x - 2})^{2} + (y - ( - 5)) {}^{2} = ({16})^{2} \\ ({x - 2})^{2} + ( {y + 5})^{2} = 256$
