Answer:
a. option is the correct answer
Answer:
option C
N ≈ 55°
Step-by-step explanation:
Given in the question a right angle triangle.
To calculate the angle N, we will use following formula
a² = b² + c² -2bcCos(A)
here,
a = 5.74
b = 4
c = 7
A = N°
Plug values in the formula
5.74² = 4² + 7² -2(4)(7)COS(N)
32.95 = 16 + 49 - 56COS(N)
32.95 = 65 - 56COS(N)
32.95 - 65 = - 56COS(N)
-32.05 = - 56COS(N)
minus will cancel out
32.05 = 56COS(N)
COS(N) = 32.05/56
COS(N) = 0.57
N = (0.57)
N = 55.08°
N ≈ 55°
Answer:
h = 18.88 inches
Step-by-step explanation:
Given that,
The circumference of a cylinder is 20 inches
The volume of the cylinder, V = 600 cubic inches
We need to find the height of the cylinder. We know that the volume of a cylinder is given by :
r is radius
We know that,
circumference = 2πr
So,
So, the height of the cylinder is 18.88 inches.
