Step-by-step explanation:
Remember, to find the area of a circle, you need to multiply pi by the radius squared
The area, 'A', of the circle is 153.86 inches squared
'π' is pi, an irrational number with a value of approximately 3.14
'r' is the radius, which is what we are solving for here
We plugged our information into the A=πr2 formula
We get "r=7", which means the radius of the circle is 7 inches!

Step-by-step explanation:
^^^^
CD = certificate of deposit (an investment)
Interest rate, i = 10% per annum (simple interest)
Principal, P = $2000 (present value)
Period, T = 3 months = 0.25 year
Simple interest formula
Interest earned = Pit
=2000*0.10*0.25
=$50
Balance at maturity (amount that investor gets after three months)
=$2000+$50
=$2050
To understand this question, you first need to determine the meaning of each value. The 320 is the total charge, which includes the money paid per hour(x) and the 70 dollars paid for the parts. The 70 dollars acts as a constant since there is no variable attached to it that will change its value. X is what is paid each hour and will be paired up with five since five hours of work is done.
Now time to write your equation. The 320 includes your 70. You don't want that since you want to find just the value of the five hours of work. So, the correct choice is B.
