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

Step-by-step explanation:
The total price for the nails is $ 12.71.
Since at the hardware store, you purchase a box of nails originally worth $ 14.99, and you have a coupon for 20% off the nails, and sales tax is 6%, to determine what is the total cost for the nails, the following calculation must be made:
- Original price - discount + tax = Total price
- (14.99 x 0.8) x 1.06 = X
- 11.992 x 1.06 = X
- 12.71 = X
Therefore, the total price for the nails is $ 12.71.
