Answer:
Step-by-step explanation:
Ok, so the formula for this is
c = 2pi(r)
So, I would multiply the radius by 2 and not pi because it seems more logical to me, but it really doesn't matter
So we insert the numbers first
c = 2(3.14)(17)
c = (3.14)(34)
c = 106.78
Round
c = 106.78 ≈ 106.8
Your answer is A.
106.8 in.
The circumference of a circle:
C = 2πr
Substitute the given information into the formula.
C = 2(3.14)(17) = 106.8
x = 7
Assuming the quadrilateral is a parallelogram, then the diagonals bisect each other.
7x - 8 = 41
7x = 49
That is 74 years.
1.5% = 0.015.
The equation for the rate of growth is P = 430,000(1.015)^n where n is the number of years.
Triple the population is 430,000 * 3 = 1,290,000, so:
1,290,000 = 430,000(1.015)^n
(1.015)^n = 1290,000 / 430,000 = 3
Taking logs of both sides:
n log 1.015 = log 3
n = log 3 / log 1.015 = 73.8 years
Those two angles have the same measure, so you have
