Answer:
A) 2341 square units
Step-by-step explanation:
Area of a regular polygon= 1/2*perimeter*apothem
Perimeter=22*8=176 units
Apothem=26.6 units
Thus:
A=1/2*176*26.6
A=88*26.6
A=2340.8
So the area of the regular octagon rounded to the nearest square unit is 2341 units^2, aka. Option A
Answer:
V_rocket = 44
ft^3 = 138.2 ft^3
Step-by-step explanation:
Volume of cone
V_cone = (1/3)*(
*(radius^2))*h
radius = 2ft
h = height of the cone = 3 ft
pi = 3.1416
V_cone = 4
ft^3
Volume cylinder
V_cylin = (
*(radius^2))*h_cyl
h_cyl = height of the cylinder = 10 ft
V_cylin = 40
ft^3
Volume rocket
V_rocket = V_cone + V_cylin = 4
ft^3 + 40
ft^3
V_rocket = 44
ft^3 = 138.2 ft^3
Answer:
4 seconds I believe
Step-by-step explanation:
Answer: 5
Step-by-step explanation:
Pythagorean Theorem = a^2 + b^2 = c^2 (hypotenuse)
the square root of 4^2 + 3^2 = c
c = 5
