For question one, you would need to use the formula pi r ^2. So first you have 4.5, which is your radius(stands for r). Then you square it, which is 20.25. Then, you multiply 20.25 with pi. Then for circumference, you do 2 x pi x the radius which is 4.5. So for area, you get 63.62. Then for circumference you get 28.27.
For question 2, it is basically the same steps but instead you a diameter, not a radius. To get the radius, divide by 2, which the radius will be 6. Then from there, the radius is 6, and you solve the question.
Answer:
0.95
Step-by-step explanation:
Let's convert this into a fraction that has a denominator of 100. In order to do so, we need to multiply the numerator and denominator both by 5 (because 20 * 5 = 100):
So, we have 95/100, which is technically 95 divided by 100. Whenever we divide something by a power of 10, like , where n is any integer, we move the decimal point of the dividend n places to the left.
Here, we have 100, which is , so we want to move the decimal point of 95 (which equals 95.0) 2 places to the left:
0.95

Answer:
A 4-year loan with a 3.5% annual simple interest rate
Step-by-step explanation:
Let L represent the number of games lost. Then 2L+17 is the number of games won. The total of games played is ...
... 98 = L + (2L+17)
... 81 = 3L . . . . . . . . subtract 17
... 27 = L . . . . . . . . divide by the coefficient of L
... 2L+17 = 2·27+17 = 71
The team had 71 wins and 27 losses.
