Answer:
The length of arc PQ is 8.1 inches.
Step-by-step explanation:
First, you have to find the angle of POQ. Given that total angles in a circle is 360°, so you have to subtract to get ∠POQ :
Next, you have to apply length of arc formula, Arc = θ/360×2×π×r where θ represents the angle of arc and r is the radius of circle :
The answer is b because 5*20=100
a. 21.141 for this pi is 3.14 so you add that and 18
b. 6.75 for this one the square root of 25 is 5. you just add 5 and 1.75
c. 7.232 sqaure root of 3 is 1.73 so add those too
d. 4.5558 pi is 3.14 and square root of 2
The correct and best answer would be letter B. To find the percent of a discount, you have to find or solve for the percent of increase from the new price to the original price. This is because you usually have the new price being given to you so you compare it with the old price to know the percent discount.
