Answer:
B. 8 ft
Step-by-step explanation:
The area of the rectangle is ...
A = LW = (16 ft)(4 ft) = 64 ft²
The area of the square in terms of its side length is ...
A = s²
For the square to have the area of the rectangle, its side length must be ...
64 ft² = s²
s = √(64 ft²) = 8 ft
A side of the square is 8 feet long.
D) 180 because there are 180 possible combinations for the marbles to be picked out
Volume of Solid = Volume of Cylinder + Volume of Cone
Volume of Cylinder = πr²h
v= 3.14 * (3)² * 6
v = 169.56
Volume of Cone = πr² h/3
v = 3.14 * (3)² * 4/3
v = 37.7
Now, V = 169.56 + 37.7 = 207.26 cm³
Hope this helps!
