C = pi * r ^squared
r = is radius
square the radius, multiple by r
or
2 x pi x r
ANSWER: Plane dropped 6097 feet in altitude.
BECAUSE: An airplane is at point A from where it continued to descend by 30° for an approximate distance of 2 miles
∠ACB = Angle of descent = 30°
Distance BC = 2 miles
Let the plane dropped the altitude = h miles
Now tan 30° =
h = 1.155 miles
h ≈ 1.16 miles
Since 1 mile = 5280 feet
1.15 miles = 5280×1.16 feet
= 6097 feet
Therefore, the plane dropped by 6097 feet vertically.
Answer:
10) x=9
11) x=25
Step-by-step explanation:
a triangle is 180º total
10) 2x+8x+90=180
10x=90
x=9
11) 3x+1+2x+2+2x+2=180
7x+5=180
7x=175
x=25
Answer:(3 * h^12 *k^2)/2
Step-by-step explanation:First distribute the exponent 6 to the terms inside, so you get 3h^12 *k^6/2k^4 ,then divide k^6 by k^4 to get k^2 on top.
3, 6 ,9, 12, 15
I think it should be 3 then add 3
