If mark and 8 of his friends went out the total of people is 9, so if you think about it 9x9=81 so the total cost of the bill was $81
An apothem is a line drawn from the centerpoint of the polygon to one side of the polygon. There is a formula for area in terms of apothem:
A = (1/2)*(Perimeter)*(Apothem)
The perimeter of the regular hexagon is just the length of one side multiplied with the number of sides. Since a hexagon has 6 sides,
P = 6(15) = 90in
A = 1/2 * 90 * 13
A = 585 square inches
The height of the cone is 4 cm (approx).
Step-by-step explanation:
Given,
The radius (r) of the cone = 4.96 cm
Volume (V) = 102 cm³
To find the height (h) of the cone.
Formula
The volume of a cone V = 
πr²h
Now,
According to the problem,
πr²h = 102
or, ×
×(4.96)²h= 102
or, h = 
or, h = 3.95 = 4 (approx)
so,
Height = 4 cm (approx)
Answer:
7 and 1
Step-by-step explanation:
√50 is the sum of the square of two legs
The answer is likely to be 7 and 1 (because 7^2 + 1^1 = 50)
