It will be 4:9 as well.
Circumference = 2πr,
r1 : r2 = 4:9 so this means that 2πr1 : 2πr2 = 4:9, because 2π = constant

Answer: 7.0596 x 10^2

I hope this helps!

If a person wanted to purchase his or her dream car, and keep it for many years, is leasing or buying the better option? Why
Pani-rosa [81]

Answer:

Leasing a car is the better option if they only want to keep it for a certain amount of years. This is because with leasing you are only paying the depreciation of the car instead of the buying price. Also, it benefits people that can't pay the down payment for the car.

alexandr402 [8]

Answer:

The Answer is C

Step-by-step explanation:

Look at each coefficient next to the degree of the radical. When inputting that number for synthetic division (From greatest degree to least) you would get 8 1 and -5. The number that is the divisor is the 6, but you have to set (x - 6) to equal zero, which would get you a number of 6.
