Answer:
4) 120π cm^2
5) 56π cm^2
6) 32π cm^2
Step-by-step explanation:
Surface Area of Cylinder = 2π + (2πr)(height)
(will use variable h for height)
4)
diameter = 8 cm
r = 0.5(diameter) = 0.5(8) = 4 cm
height = 11 cm
2π + (2π)(4)(11)
= 2π(16) + 2π(44)
= 32π + 88π
= 120π cm^2
5)
diameter = 8 cm
r = 0.5(diameter) = 0.5(8) = 4 cm
height = 6 cm
2π + (2π)(4)(6)
= 2π(16) + 2π(12)
= 32π + 24π
= 56π cm^2
6)
diameter = 6 cm
r = 0.5(diameter) = 0.5(6) = 3 cm
height = 7 cm
2π + (2π)(3)(7)
= 2π(9) + 2π(7)
= 18π + 14π
= 32π cm^2

Given:
The measure of three sides of a triangle are 8, 7 and 14.
To find:
The measure of the angle opposite the side of length 8.
Solution:
According to the Law of Cosine:
Let a=8, b=7 and c=14, then by using Law of Cosine, we get
Taking cos inverse on both sides.
Therefore, the measure of the angle opposite the side of length 8 is 22.6 degrees.
