Answer:
D
Step-by-step explanation:
The formula for the area of a segment is ...
A = 1/2r²(θ -sin(θ))
for radius r and central angle θ.
Here, we have θ = π/2, so this becomes ...
A = 1/2r²(π/2 -1) . . . . . matches choice D
(4, 2) ----> ( 2, 1)
(4 - 2, (2 - 1) ----> (2, 1)
That's a vertical -1 and horizontal of -2.
That's the last choice.
Answer:
15) f = 18
3f = 54
6f = 108
16) k = 69
Step-by-step explanation:
15)
3f + 6f + f = 180
10f= 180
f = 18
16)
42 + k + k = 180
42 + 2k = 180
2k = 138
k = 69
Okay find the volume of the cube: 5*5*5=125 inches cubed
Now find the volume of the spheres: 4/3pir^3=24/3pi
125/(24pi/3) = 4.97 So you can make 4 balls
Do you need the answer now ?
