0.275862069 or 0.27 I think
You need to use the law of cosine:
B^2 = A^2 + C^2 - 2ACcos(b)
55^2 = 90^2 + 50^2 - 2(50)(90)cos(b)
0.841666 = cos(b)
b = 32.68
First convert the measurement of feet to inches. There are 12 inches in a foot. So 24 feet becomes 288 inches.
Now multiply the cost by the inches. $0.25 x 288 = 78
So it will cost $78.00 in total.
Hope this helps! :D

Answer:
167.6 cm³
Step-by-step explanation:
the volume of a cone :
ground area × height / 3 = pi×r² × height / 3
r = 4 cm
height = 10 cm
pi×4² × 10 / 3 = pi×16×10/3 = pi×160/3 = 167.6 cm³
