Altitude = 90* Angle
15^2+b^2 = 39^2
225+b^2 = 1521
1296 = b^2
36= b
15^2 + b^2 = 17^2
225 +b^2 = 289
64 = b^2
8 = b
36 + 8 = 44
39+17 = 56
56 is greater then 44
Triangle Inequality Theorem Proves
So QR = 44
The function is increasing on the intervals (-infinity, -2.5] and [1, infinity)
Answer:
Approximately: 200.76π or 630.39
Step-by-step explanation:
Surface area for sphere formula: A = 4π(r^2)
36π = 4(r^2)
(36/4)π = [4(r^2)]/4
9π = r^2
28.26 = r^2 (since π equals 3.14)
√28.26 = √r^2
r ≈ 5.32
Volume for sphere formula: V = 4/3(π)(r^3)
V = 4/3(π)(5.32^3)
V ≈ 4/3(π)(150.57)
V ≈ 200.76π
or
V ≈ 630.39
