Answer:

r = 8

Step-by-step explanation:

The circumference of a circle is given by :

C=2\pi r ...(1)

We need to find the value of r when C = 16π

Solving equation (1)

r=\dfrac{C}{2\pi}\\\\r=\dfrac{16\pi}{2\pi}\\\\r=8

So, the value of r is 8. Hence, the correct option is (b).

In a sale there is 25% off all prices a chair costs 90 in the sale. how much was it before the sale?
kipiarov [429]
First, set up a porportion to help you answer the question. Put percent paid/100 is equal to sale price/ original. The percent paid would be 75% because if the chair is 25% OFF then you would pay 75%. So then you would define your variable (I'll use x). X equals the original price. So, 75/100 equals 90/x. Then you can reduce 75/100 to 3/4 and cross multiply to get 3x=360. Then you would divide both sides by 3 to get x=120. So the original price of the chair was $120
