Answer:
C
Step-by-step explanation:
6 + 3(x + 4)
= 6 + 3x + 12
= 3x + 18
Answer:
what is half of 30 percent?
Step-by-step explanation:
and that might give you the half of 30 percent and all you will have to do is figure out how 30 percent is all toghter and then add the anthor numbers and also but lastly put in on a experession in simplifed form.
The circumference of the outer circle is greater than that of the inner circle by 18.86 feet.
<h3>What is Circle?</h3>
A circle is a round 2-dimensional shape. It is a closed shape with a distance from center to circumference termed as radius 'r' and distance from one point on the circumference to another point passing through center termed as diameter 'd'.
The circumference of the inner circle is 88 ft.
Circumference of a Circle = 2πr
2πr = 88
2 X 22/7 X r = 88
r = 88 X 7 / 44
r = 14 ft.
Radius of the inner circle = 14 feet
If the distance between the inner circle and the outer circle is 3 ft, the radius of the outer circle = 14+3 = 17 feet.
circumference of the outer Circle = 2πr
= 2 X 22/7 X 17
= 106.86 ft.
Difference in Circumference = 106.86 - 88 = 18.86 feet
Thus, the circumference of the outer circle is greater than that of the inner circle by 18.86 feet.

What grade homework is that?
1. Know that: (1) in 28 miles, there are 147,840 ft because 28*5280, (2) radius is 7/6 because that is (2 1/3)/2, (3) C=2(pi)(7/6) or pi*7:3
2. To find revolutions per minute, you take 147,840 and divide it by the circumference to get revolutions per hour, which is about 20168.11439. Then, divide this by 60 to find revolutions per minute: 336.1352398 revolutions/min.
3. Then, to find the angular measure in radians you take the revolutions per minute and multiply it by 2pi.
