The circumference of oc is 56 cm. what is the length of ab (the minor arc)?

Length of arc AB is 14. So, option E is correct

Step-by-step explanation:

Circumference of circle == 56 cm

We need to find length of arc AB?

Formula used will be l = rФ

We know, C = 2πr

56 = 2πr

56/2π = r

=> r = 8.91

Ф = 90° = 1.57 radians

So, l= rФ

l = 8.91 * 1.57

l = 13.98 = 14

So, Option E is correct

answer:

it will cost 480 dollars to refurbish the larger wood floor

step-by-step explanation:

as it's a ratio of 4 that costs 384 dollars, divide the price by the ratio

384 / 4 = 96 dollars

96 dollars per unit of the ratio

now to get the price to refurbish the larger wood floor, times the price by the units

96 * 5 = 480
