Answer:
Step-by-step explanation:
A
If 3 inches represents 15 miles, then that means 1 inch represents 15/3 = 5 miles. That means that 5 inches represents 5 * 5 = 25 miles.
The answer is choice (A).
PART ;
......Circle A.................
Circumference - 2 pi r
25.12 = 2pi(4)
25.12 = 8i
Divide both sides by 8!!
3.14=pi
...Circle B.....................
Circumference = 2 pi r
9.42 = 2pi(3/2)
9.42 = 3pi
Divide both sides by 3!!!
3.14 = pi
PART B
.............Circle A...............
A=pi r ^2
50.24 = pi(4)^2
50.24=16pi
Divide both sides by 16!!!
3.14=pi
.............Circle B.............
A=pi r^2
7.065=pi(3/2)^2
7.065= 9pi/4
Divide both sides by 9/4!!!
3.14=pi
PART C
They used exactly 3.14 for the value of pi in CIRCLE A and B to get the circumference and the area :D
I hope this makes sense!!!
When I wrote 'pi', it was supposed to be the symbol for pi.
Answer: 79.02
Step-by-step explanation:
set present value to 0
set future value to 300000
set number of time periods to 35 * 12 = 420
set interest rate percent per time period to 10/12 = 0.833333.
