Advanced ($10): A
Door ($13): D
Money: 10A + 13D = 544 ⇒ 1(10A + 13D = 544) ⇒ 10A + 13D = 544
Quantity: A + D = 46 ⇒ -10(A + D = 46) ⇒ <u> -10A - 10D</u> = <u>-460 </u>
3D = 84
D = 28
Quantity: A + D = 46 ⇒ A + (28) = 46 ⇒ A = 18
Answer: advanced = 18 people, at the door = 28 people
Answer:
100.79
Step-by-step explanation:
<h3><u>Given Information :</u></h3>
- Radius of the turbine = 32 m
- π = 3
<h3 /><h3><u>To calculate :</u></h3>
- Area covered by blade when the turbine makes 1 revolution.
<h3><u>Calculation :</u></h3>
We know that,
Therefore,
- Correct option is <u>option 4th.</u>
Answer: 8pi
--------------------------------------
Explanation:
A = 16pi is the area, which means
A = pi*r^2
16pi = pi*r^2
16 = r^2
r^2 = 16
r = sqrt(16)
r = 4
is the radius
Use this to find the circumference C
C = 2*pi*r
C = 2*pi*4
C = 8pi
The exact circumference is 8pi inches long
I think it's 115
180-65= 115=<BCD
