Distance after 1 minute = speed * time = 275 * 60 = 16,500 feet
Let the altitude of the plane be y, then
sin 18 = y/16500
y = 16500 sin 18 = 5,098.78 feet
This is the concept of graphs and volume of the solid figures, given that the triangle J,K,L was rotated along the x-axis, the resultant figure was cone with with radius of 5 units and a height of 4 units;
The volume of a cone is given by;
V=πr^2(h/3)
r=5 units
h=4 units
V=π*5^2*(4/3)
V=104.72 units^3
the answer is B]
Answer:
.D. 4√2 cm
Step-by-step explanation:
With reference angle 45°
base (b) = 4 cm
hypotenuse (h) = AC
Now
Cos 45° = b /h
1/√2 = 4 / AC
AC = 4√2 cm
